Transitively consume the property from linked dependents.
Implement configuration-specific support by following the pattern
set out for compile definitions and includes in cmQtAutoGenerators.
Implement support for origin-tracking with CMAKE_DEBUG_TARGET_PROPERTIES.
This is motivated by the needs of KDE, which provides a separate
translation system based on gettext instead of the Qt linguist
translation system. The Qt uic tool provides command line options
for configuring the method used to translate text, and to add an
include directive to the generated file to provide the method.
http://thread.gmane.org/gmane.comp.kde.devel.frameworks/7930/focus=7992
Implement the interface to provide the uic options as a usage-requirement
on the KI18n target, as designed for KDE.
Creates a hierarchy of WiX features from CPack components and component groups.
Switch to the FeatureTree UI in case components have been defined.
Handles the component REQUIRE and HIDDEN options
and the component group EXPANDED option.
Diagnostics which check the sanity of exported include paths
previously skipped over any path containing a generator expression.
Introduce a policy to issue an error message in such cases.
The export files created in the OLD behavior are not usable, because
they contain relative paths or paths to the source or build location
which are not suitable for use on installation. CMake will report an
error on import.
Code such as
target_include_directories(foo INTERFACE
$<INSTALL_INTERFACE:include$<FOO>>
)
should be treated as a relative directory, despite the genex, after
the INSTALL_INTERFACE is stripped away.
Previously, this would generate a relative directory on export, which
would be an error on import, so no policy is needed.
Code such as
install(TARGETS ...
INCLUDES DESTINATION $<INSTALL_INTERFACE:include>
)
should behave as if the INSTALL_INTERFACE wrapper were not present.
In code such as
install(TARGETS ...
INCLUDES DESTINATION $<FOO>include
)
the generator expressions are evaluated at generate-time. Delay
determining whether each entry is a relative path until after
the generator expressions are evaluated. Such relative paths
are based relative to the CMAKE_INSTALL_PREFIX.
Treat paths which are relative and which contain a generator
expression which is not at the beginning as relative to the
source directory.
This matches the behavior of paths which are relative but contain
no generator expression at all.
Previously this would generate a relative path with the IMPORTED
target on export(), which would be a reported as a non-existent
path on import. If used directly in the buildsystem, it would be
reported as a relative path, which is also an error. There is no
need for a policy in this case.
Add the "-e" option to build.make invocations of wmake as part of
the silencing flags. From "wmake /?":
-e erase files after error (no prompt)
This prevents test timeouts on error.
As an INTERFACE_LIBRARY has no direct link dependencies, we can
short-circuit in cmGeneratorExpressionEvaluator and
in cmGlobalGenerator::CheckLocalGenerators.
As they do not generate any output directly, any generate- or install-
related code acn also be short-circuited. Many of the local generators
already do this.
Because only INTERFACE related properties make sense on INTERFACE_LIBRARY
targets, avoid setting other properties, for example via defaults.
Just enough to reach the BuildMacContentDirectory method and the
NeedRelinkBeforeInstall methods.
In the future, those methods can be moved to cmGeneratorTarget.
Define a custom ordering functor to deterministically and strictly
order the cmTarget* key. Otherwise the order would be dependent on
runtime pointer values, which breaks assumptions of some generators.
The functor orders first by target name, and then by directory. Multiple
global targets may have the same name, such as edit_cache, but their
directory differentiates them.
This allows avoiding error-prone hard-coding of literal
string lengths.
Borland is not able to process the template version of this
method. Make it use the macro version instead. This means
that Borland will also use the macro versions of cmArray*.
Download http://www.gnu.org/licenses/old-licenses/lgpl-2.1.txt and place
it as Licenses/LGPLv2.1.txt in our source tree. When building cmake-gui,
use option CMake_GUI_DISTRIBUTE_WITH_Qt_LGPL to enable notification
in the "About" dialog of how the distribution of Qt is licensed.
Install the license file as ${CMAKE_ROOT}/Licenses/LGPLv2.1.txt so that
the dialog can display a path to it.
This variable can be useful in cross-compiling contexts where the
sysroot is read-only or where the sysroot should otherwise remain
pristine.
If the new CMAKE_STAGING_PREFIX variable is set, it is used instead
of CMAKE_INSTALL_PREFIX when generating the installation rules in
cmake_install.cmake.
This way, the CMAKE_INSTALL_PREFIX variable
always refers to the installation prefix on the target device, regardless
of whether host==target.
If any -rpath paths passed to the linker contain the CMAKE_STAGING_PREFIX,
the matching path fragments are replaced with the CMAKE_INSTALL_PREFIX.
Matching paths in the -rpath-link are not transformed.
The cross-prefix usr-move workaround is assumed not to require extension
regarding CMAKE_STAGING_PREFIX. The staging area is a single prefix, so
there is no scope for cross-prefix symlinks. The CMAKE_INSTALL_PREFIX
is still used to determine the workaround path, and that variable
remains the relevant one even if CMAKE_STAGING_PREFIX is used. If the
generated export files are deployed to the target, the workaround
will still be in place, and still be employed if required.

76552d5 Add compiler target compile options.
f41ecd1 CMakeDetermineCompilerId: Look for internal file only on host
As CMAKE_ROOT_FIND_PATH can be a list, a new CMAKE_SYSROOT is
introduced, which is never a list.
The contents of this variable is passed to supporting compilers
as --sysroot. It is also accounted for when processing implicit
link directories reported by the compiler, and when generating
RPATH information.
Clang can compile code, but uses the gcc tools for other tasks such
as linking. The -gcc-toolchain option can be used for that, but
generalize so that other compilers can be treated the same.
If such a location is specified, use it as a hint for finding
the binutils executables.
For clang, this allows passing -target <triple> to the compiler, and
for qcc, -V<arch> using toolchain files containing something like
set(triple arm-linux-gnueabihf)
set(CMAKE_C_COMPILER "/usr/bin/clang")
set(CMAKE_C_COMPILER_TARGET ${triple})
set(CMAKE_CXX_COMPILER "/usr/bin/clang++")
set(CMAKE_CXX_COMPILER_TARGET ${triple})
or
set(arch gcc_ntoarmv7le)
set(CMAKE_C_COMPILER /opt/qnx650/host/linux/x86/usr/bin/qcc)
set(CMAKE_C_COMPILER_TARGET ${arch})
set(CMAKE_CXX_COMPILER /opt/qnx650/host/linux/x86/usr/bin/QCC)
set(CMAKE_CXX_COMPILER_TARGET ${arch})
Both clang and qcc are inherently cross compiler( driver)s.
When cross-compiling with clang, use the CMAKE_${lang}_COMPILER_TARGET
as the _CMAKE_TOOLCHAIN_PREFIX to find the appropriate binutils.
When cross-compiling with QNX qcc, use the CMAKE_${lang}_COMPILER_TARGET
to set the appropriate _CMAKE_TOOLCHAIN_PREFIX.
Some generators can use the any enabled languages to add extra support
in the relevant build tool. One such is Eclipse since there are many
plugins available for various languages.
After warning that a help output format is no longer supported, fix the
return value from cmDocumentation::CheckOptions to indicate that it was
still a help option that was parsed. Otherwise CMake moves on to treat
the help output file name as a source tree and complains that it does
not exist.

Teach add_custom_target to check the policy too. Extend the policy to
disallow reserved target names that we use for builtin targets like
"all".
Extend the RunCMake.CMP0037 test to cover these cases.
Fix CMAKE_<LANG>_CREATE_SHARED_LIBRARY_FORBIDDEN_FLAGS implementation to
only remove whole flags. Without this n the Mac we were incorrectly
removing -w from -Wno-write-strings.
Since commit 42ba1b08 (VS: Separate compiler and linker PDB files,
2013-04-05) the VS generators no longer add ProgramDataBaseFileName.
Therefore we should allow projects to do so by mapping the /Fd option.
For VS >= 10 our flag tables map /Fd to ProgramDataBaseFileName already.
Add the mapping for VS 7, 8, and 9.
Drop the "Modules/CMakeVS*FindMake.cmake" files. Override the
cmGlobalGenerator::FindMakeProgram method for VS generators to use their
internal APIs to locate the build tool. Set the CMAKE_MAKE_PROGRAM as a
normal variable for use by project code, but do not cache it. This will
allow CMake and CTest to select the proper tool at build time.
The --build-options option consumes all following arguments until either
--build-target or --test-command. Fix the logic to allow this to be
zero options.
GenerateBuildCommand now knows how to lookup CMAKE_MAKE_PROGRAM or
choose a generator-provided default build tool. Therefore the
--build-makeprogram can now be optional and simply override the
default selection when provided.
Note that with --build-nocmake we now need to load the cache in order to
make the CMAKE_MAKE_PROGRAM entry available to GenerateBuildCommand.
Code paths that look up CMAKE_MAKE_PROGRAM from the cache only to
pass it to Build, which only passes it to GenerateBuildCommand,
no longer need to do so. GenerateBuildCommand now knows how to
look up CMAKE_MAKE_PROGRAM in the cache when no explicit value
is given, so simply pass 0 now.
Add a cmGlobalGenerator::SelectMakeProgram method to select a
caller-provided make program, the CMAKE_MAKE_PROGRAM cache entry, or a
generator-provided default. Call it from all implementations of the
GenerateBuildCommand method with the corresponding generator's default,
if any.
Historically these were both added for the Makefile and Visual Studio
generators, respectively. Later the VS generators started using the
CMAKE_MAKE_PROGRAM cache entry to find the IDE build tool, and the
CMAKE_BUILD_TOOL was simply set as an alias.
Fix the documentation to explain that CMAKE_MAKE_PROGRAM is the modern
variable and that CMAKE_BUILD_TOOL is the compatibility alias, not the
other way around. Replace uses of CMAKE_BUILD_TOOL with
CMAKE_MAKE_PROGRAM in CMake-provided modules. Nothing needs to lookup
CMAKE_BUILD_TOOL in the cache, so simply set it as a normal variable.
All cmGlobalGenerator::GenerateBuildCommand call sites that need to
produce a string now generate "cmake --build" commands. The remaining
call sites immediately pass the result to cmSystemTools::RunSingleCommand.
Avoid the intermediate string and argument parsing by directly producing a
vector of strings. Also drop the ignoreErrors argument because no call
sites remain that use it.
This avoids requiring cmGlobalGenerator::GenerateBuildCommand to produce
a string so that it can be later refactored to produce a vector with no
quoting or escaping. It also makes the ctest_build command match what
"ctest -T Build" would run in a build tree configured with the new
build_command() command behavior. It also ensures that the native build
tool used matches that selected by the configuration of the tree to be
built.
Re-implement the build_command() command to use "cmake --build" instead
of generating a native build tool invocation directly. This command
will internally invoke the proper native build tool.
This avoids requiring cmGlobalGenerator::GenerateBuildCommand to produce
a string so that it can be later refactored to produce a vector with no
quoting or escaping. It will also allow us to later teach CMake to
delay the decision about which build tool to invoke until after the
project build system is generated to disk. For example, on Visual
Studio 10 and above the preferred command-line tool is MSBuild, but we
need to fall back to devenv if the .sln has Intel Fortran .vfproj files.
Create a GenerateCMakeBuildCommand method to generate a command-line
string invoking "cmake --build" for a given target and configuration.
Optionally allow the "-i" make flag and additional native options.
This is a virtual method that is overridden by every generator
subclass. The base class implementation should never be called,
so replace it with a dummy implementation.

Always name the application bundle "CMake.app". Users can rename it
after installation if they wish. This is the typical approach used by
OS X applications, including Xcode. It allows CMake to be upgraded
without manually re-running CMake in every build tree to update the path
to CMake. It also makes the executable location in the CMake build tree
more predicatable.
Refactor edit_cache tool selection to ask each global generator for its
preference. Teach the Ninja generator to always use cmake-gui because
Ninja by design cannot run interactive terminal dialogs like ccmake.
Teach the Makefile generator to use cmake-gui when also using an "extra"
generator whose IDE has no terminal to run ccmake, and otherwise fall
back to CMAKE_EDIT_COMMAND selection for normal Makefile build systems.

Teach it to compute the locations of cmake, ctest, cpack, ccmake, and
cmake-gui executables, and the location of CMAKE_ROOT. Provide this
information from static cmSystemTools::Get<resource>() methods.
Refactor code that needs these locations to use the new APIs.
Teach FindCMakeResources to use the OS X system API to lookup the
executable location. When running from the CMake build tree itself,
leave a file in the tree that FindCMakeResources can use to read the
location of the source tree. This avoids the need to compile the source
tree location into a binary that may be installed and used without the
source tree.
Teach the QtDialog on OS X to create a "cmake-gui" symlink in the build
tree next to "cmake" and the other tools, as is already done in the
install tree for the application bundle. This ensures a consistent set
of executables are available in one directory.
Replace the std::map<>::clear() method with one that first deletes
the cmExportSet instances held by each map entry, and then clears.
Otherwise the cmGlobalGenerator::ClearGeneratorMembers added by
commit 5cf1120f (cmGlobalGenerator: Refactor member cleanup between
configures, 2013-11-04) leaks the cmExportSet instances.
This change causes the GetLinkInterfaceDependentStringProperty method,
called in SetupAutoGenerateTarget, after the creation of generator
targets. In CMake 4.0, the GetLinkInterfaceDependentStringProperty
will move to the cmGeneratorTarget class, and this patch is a necessary
prerequisite to that.
The SetupAutoGenerateTarget method will soon be invoked at a later
time in a followup commit. We need to ensure that we create the
utility autogen target early.
In commit 18412153 (Refactor cmTarget::GetCompileDefinitions...,
2013-06-06) cmQtAutomoc was refactored to get all compile definitions
from the target instead of separately asking the target and querying the
directory-level COMPILE_DEFINITIONS property value. While the
generation process does integrate directory-level COMPILE_DEFINITIONS
into the target definitions, this did not happen until after Automoc
targets are constructed. Therefore the commit regressed use of
directory-level definitions in Automoc targets.
Factor the definition finalization logic out from the
cmGlobalGenerator::CreateGeneratorTargets method into a new
cmGlobalGenerator::FinalizeTargetCompileDefinitions method and call it
before constructing Automoc targets. This will place the
directory-level definitions into the target in time to use them for the
Automoc targets.
Extend the QtAutomoc test to cover this case.
Do not access an argument index not known to exist.
Port the change from commit 9ef66f2b (cmake: Validate -E cmake_automoc
argument count, 2013-11-05) to the new location of the code.
Factor member cleanup out from cmGlobalGenerator::Configure and the
destructor into a dedicated helper to avoid duplication. This fixes
clearing of BuildExportSets between configures.
In the CMake interactive dialogs cmGlobalGenerator::Configure may
run more than once. Clear the cmGlobalGenerator::EvaluationFiles
data between configures to avoid accessing deleted data.

Resolve conflict in Source/cmTargetLinkLibrariesCommand.h by dropping
the documentation change. We will make the same change in the new
location of the same documentation in a separate commit.
Resolve conflicts in
Tests/RunCMake/CMP0022/CMP0022-WARN-empty-old-stderr.txt
Tests/RunCMake/CMP0022/RunCMakeTest.cmake
by taking the side from the 'policy-CMP0022-fixes' branch.
Since cmTarget::ComputeLinkInterface is called separately for each
"head" target that links a target, the warning we produce when
CMP0022 is not set could be repeated. Add explicit logic to allow
the warning to appear at most once. Multiple copies of the warning
for the same target are almost always identical and therefore
redundant. In the rare case that two copies of the warning are
different, the second can appear in a future run after the first
is fixed.
When cmExportFileGenerator::SetImportLinkInterface exports the old
LINK_INTERFACE_LIBRARIES property values it skips doing so for
non-linkable targets because target->GetLinkInterface returns NULL for
such targets.
Since cmExportFileGenerator::PopulateInterfaceLinkLibrariesProperty
looks at the INTERFACE_LINK_LIBRARIES property directly instead of using
the computed link interface, teach it to skip exporting the property if
target->IsLinkable returns false.
Extend the RunCMake.CMP0022 test with a case covering this. Simply
export an executable target that links to a library that is not
exported.
The CMP0022 NEW behavior is that the INTERFACE_LINK_LIBRARIES property
exactly defines the link interface. The plain target_link_libraries
signature says linking is transitive by default, so it should populate
the property.
Teach the target_link_libraries plain signature to populate the
INTERFACE_LINK_LIBRARIES regardless of the CMP0022 setting. Refactor
the cmTarget::ComputeLinkInterface checks that warn when the policy is
not set to compare the new property to either the explicitly set old
link interface properties or the link implementation fallback for all
linkable target types, not just static libraries.
This fixes a regression in 2.8.12.0 that caused target_link_libraries to
not implement transitive linking in the plain signature once the policy
CMP0022 is set to NEW.

If a symlink fails to extract and the host system is Windows then report

Report the names with the year to the list of available generators so

generator from the "-G" option or from an existing CMAKE_GENERATOR cache
entry, recognize names without the years for compatibility and map them
to the names with years.

3e04946 Require CMAKE_<LANG>_COMPILER to be found as a full path
6007f7c CMakeDetermineCompilerId: Always use compiler detected from IDE

other logic to assume the full path to the compiler tool is available.
The Makefile generators already rejected CMAKE_<LANG>_COMPILER values
that did not name an existing compiler. Extend this error message to
all generators, make it occur as early as possible, and improve the
message with advice about how to set the compiler. If the full path to
the compiler is not known, finish enabling languages with a fatal error
so configuration does not continue.
For now, allow the RC language compiler to not be a full path. Later we
will need to detect the full path to "rc" under the VS IDE.

toward this server for the duration of the test.
Only valid target names or generator expressions may appear in
the target field of a LINK_ONLY expression.
Other content like link flags should still be added to that property
(wrapped in config-specific generator expressions), but not wrapped
in LINK_ONLY. Otherwise undue warnings would be issued for the
policy CMP0022.
The LINK_ONLY expression only has an effect for actual target
names anyway, so there is no logical deficit.
Since commit c9a5f34b (Cleanup use of CMake version in install
destinations, 2013-09-26) we use the full CMake version in default
install destinations. For rapidly changing versions of the form
<major>.<minor>.<patch>.<date>-g<commit>[-dirty]
used by developers this is too granular. Instead use just
<major>.<minor>.<patch>
as the version for default install destinations. This will still
be granular enough for unique directories in releases.
On Cygwin continue to use the full ${CMake_VERSION} as was the case
prior to the above-mentioned commit.
The source files are already processed by cmQtAutomoc to look for
moc includes, so extend that to also look for ui_ includes and
find corresponding .ui files to process.
This replaces the need to invoke qt4_wrap_ui().
As the ui files are not likely to be part of the SOURCES of the
target, store the options associated with them separately in the
cmMakefile for querying during the autogen run.
There is no need for a "cmake_automoc" backward compatibility command
because it is internal, undocumented, and only executed from a matching
version of cmake.
When using the boost MPL library, one can set a define to increase
the limit of how many variadic elements should be supported. The
default for BOOST_MPL_LIMIT_VECTOR_SIZE is 20:
http://www.boost.org/doc/libs/1_36_0/libs/mpl/doc/refmanual/limit-vector-size.html
If the foo library requires that to be set to 30, and the independent
bar library requires it to be set to 40, consumers of both need to set
it to 40.
add_library(foo INTERFACE)
set_property(TARGET foo PROPERTY INTERFACE_boost_mpl_vector_size 30)
set_property(TARGET foo PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
target_compile_definitions(foo INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)
add_library(bar INTERFACE)
set_property(TARGET bar PROPERTY INTERFACE_boost_mpl_vector_size 40)
# Technically the next two lines are redundant, but as foo and bar are
# independent, they both set these interfaces.
set_property(TARGET bar PROPERTY COMPATIBLE_INTERFACE_NUMBER_MAX boost_mpl_vector_size)
target_compile_definitions(bar INTERFACE BOOST_MPL_LIMIT_VECTOR_SIZE=$<TARGET_PROPERTY:boost_mpl_vector_size>)
add_executable(user)
target_link_libraries(user foo bar)
Because the TARGET_PROPERTY reads the boost_mpl_vector_size property
from the HEAD of the dependency graph (the user target), and because
that property appears in the COMPATIBLE_INTERFACE_NUMBER_MAX of
the dependencies of the user target, the maximum value for it is
chosen for the compile definition, ie, 40.
There are also use-cases for choosing the minimum value of a number.
In Qt, deprecated API can be disabled by version. Setting the
definition QT_DISABLE_DEPRECATED_BEFORE=0 disables no deprecated
API. Setting it to 0x501000 disables API which was deprecated before
Qt 5.1 etc.
If two dependencies require the use of API which was deprecated in
different Qt versions, then COMPATIBLE_INTERFACE_NUMBER_MIN can be
used to ensure that both can compile.
Otherwise, in the string case, we would get a null pointer instead
of the implied empty string. That will become relevant when the
comparison result is used.
When scanning CMake module files for .rst comments, recognize
bracket comments starting in ".rst:" too. For example:
#[[.rst:
Include the bracket comment content terminated by the closing bracket.
Exclude the line containing the bracket if it starts in "#".
Teach the CMakeLib.testRST test to cover multiple bracket lengths
and ending brackets on lines with and without "#".
Update the cmake-developer.7 manual to document the bracket-comment
syntax for .rst documentation.
Teach the CMake language lexer to treat the \-LF pair terminating a
line ending in an odd number of backslashes inside a quoted argument
as a continuation. Drop the pair from the returned quoted argument
token text. This will allow long lines inside quoted argument
strings to be divided across multiple lines in the source file.
It will also allow quoted argument text to start on the line after
the opening quote. For example, the code:
set(x "\
...")
sets variable "x" to the value "..." with no opening newline.
Previously an odd number of backslashes at the end of a line inside
a quoted argument would put a \-LF pair (or a \-CR pair) literally
in the argument. Then the command-argument evaluator would complain
that the \-escape sequence is invalid. Therefore this syntax is
available to use without changing behavior of valid existing code.
Teach the RunCMake.Syntax test to cover cases of quoted arguments
with lines ending in \, \\, and \\\. Odd counts are continuations.
Drop all behavior activated by setting CMAKE_BACKWARDS_COMPATIBILITY to
a value lower than 2.4, and generate an error when projects or the user
attempt to do so. In the error suggest using a CMake 2.8.x release.
Teach cmake_minimum_required to warn about projects that do not require
at least CMake 2.4. They are not supported by CMake >= 3.0.
Replace the documentation of CMAKE_BACKWARDS_COMPATIBILITY with a
reference to policy CMP0001.

Other warnings for the same policy already have similar output since
commit 81d2793e (Add differing target property content to policy CMP0022
warning, 2013-09-11).
The cmRST implementation and the list of capabilities documented in the
cmake-developer.7 manual must be kept in sync. Add a note to each file
to reference the other.
Add cmCommand::Disallowed helper to check the setting of a policy that
disallows the command. Add a RunCMake.DisallowedCommands test
placeholder. Add a Help/policy/DISALLOWED_COMMAND.txt file for
inclusion by each policy document to avoid duplication of the common
text.
Teach cmRST to recognize non-markup lines ending in '::' followed by a
blank line as starting a literal block. Record the whole block as if it
were a literal block directive and print it just like a code block.
Extend the CMakeLib.testRST test to cover such cases.
Move the ProcessDirectiveParsedLiteral and ProcessDirectiveCodeBlock
method internals into an OutputMarkupLines helper. Pass through it a
new "inlineMarkup" parameter and teach OutputLine to understand it.
When false, do not process inline markup. Extend the CMakeLib.testRST
test to cover the two cases.
CMake/Source/cmGeneratorExpressionParser.cxx: In member function ‘void cmGeneratorExpressionParser::ParseGeneratorExpression(std::vector<cmGeneratorExpressionEvaluator*>&)’:
CMake/Source/cmGeneratorExpressionParser.cxx:116:55: warning: conversion to ‘unsigned int’ from ‘long int’ may alter its value [-Wconversion]
CMake/Source/cmGeneratorExpressionParser.cxx:240:39: warning: conversion to ‘int’ from ‘long int’ may alter its value [-Wconversion]
Add a string(CONCAT) command to simply concatenate input arguments
together. This will be useful for combining strings from different
quoting syntaxes. Add a RunCMake.string test covering these cases.
Teach the Xcode generator to set 'lastKnownFileType' to be 'folder' for
file references that are directories. If you set 'explicitFileType' to
'sourcecode', then Xcode cannot browse the directory.
Introduce a policy to control the behavior.
The AliasTargets unit test already tests that using a
double-semicolon in the name is not an error. Change the ExportImport
test to use a namespace with a double-semicolon too.
The result is that the depends of the target are created.
So,
add_library(somelib foo.cpp)
add_library(anotherlib EXCLUDE_FROM_ALL foo.cpp)
add_library(extra EXCLUDE_FROM_ALL foo.cpp)
target_link_libraries(anotherlib extra)
add_library(iface INTERFACE)
target_link_libraries(iface INTERFACE anotherlib)
Executing 'make iface' will result in the anotherlib and extra targets
being made.
Adding a regular executable to the INTERFACE of an INTERFACE_LIBRARY
will not result in the executable being built with 'make iface' because
of the logic in cmComputeTargetDepends::AddTargetDepend.
So far, this is implemented only for the Makefile generator. Other
generators will follow if this feature is possible for them.
Make INTERFACE_LIBRARY targets part of the all target by default.
Test this by building the all target and making the expected library
EXCLUDE_FROM_ALL.
Teach the VS 7-9 generators to honor the
VS_DOTNET_TARGET_FRAMEWORK_VERSION
target property. This was already done for VS >= 10 by commit cfe6300a
(VS: Add support for .NET target framework version, 2013-06-14).

These policies were introduced after 2.8.12 in anticipation of 2.8.13.
However, we've now decided the next release will be 3.0.0, so update the
version of introduction accordingly.
The full policy documentation was moved to Help/policy/*.rst by commit
f051814e (Convert builtin help to reStructuredText source files,
2013-10-15). We no longer need the builtin string literals.
In commit 87cc62ca (Drop "full" documentation output types, 2013-09-13)
we dropped code using the LongDescription field of policy definitions.
We need to follow it up with a change similar to commit 399e9c46 (Drop
builtin property documentation, 2013-09-16) to remove the policy
documentation. Do that now. Keep the short description as it is used
in policy error and warning messages.
This has not been allowed since they were introduced in
commit 91438222 (target_link_libraries: Add LINK_(PUBLIC|PRIVATE)
options, 2011-10-07), but allowing this form makes it more compatible
with the newer PUBLIC and PRIVATE keywords.
Teach the CMake language parser to recognize Lua-style "long bracket"
arguments. These start with two '[' separated by zero or more '='
characters e.g. "[[" or "[=[" or "[==[". They end with two ']'
separated by the same number of '=' as the opening bracket. There is no
nesting of brackets of the same level (number of '='). No escapes,
variable expansion, or other processing is performed on the content
between such brackets so they always represent exactly one argument.
Also teach CMake to parse and ignore "long comment" syntax. A long
comment starts with "#" immediately followed by an opening long bracket.
It ends at the matching close long bracket.
Teach the RunCMake.Syntax test to cover long bracket and long comment
cases.
Read input files in binary mode instead of text mode and convert CRLF
newlines to LF newlines explicitly in our own buffer. This is necessary
to read CMake source files with CRLF newlines on platforms whose C
runtime libraries do not transform newlines in text mode. For example,
a Cygwin or Linux binary may not transform CRLF -> LF in files read from
a Windows filesystem. Perform the conversion ourselves to ensure that
multi-line string literals in CMake source files have LF newlines
everywhere.
Teach the lexer to read a UTF-8, UTF-16 BE/LE, or UTF-32 BE/LE
Byte-Order-Mark from the start of a file if any is present. Report an
error on files using UTF-16 or UTF-32 and accept a UTF-8 or missing BOM.
Teach the lexer to treat a single letter as an identifier instead of an
unquoted argument. Outside of a command invocation, the parser treats
an identifier as a command name and an unquoted argument as an error.
Inside of a command invocation, the parser treats an identifier as an
unquoted argument. Therefore this change to the lexer will make what
was previously an error case work with no other behavioral change.

command line e.g. "cmake echo -E message" or "cmake echo message -E",
but no one should be using it as it was not documented and looks
strange.

...
Drop all DefineProperty calls for non-chained properties. Drop the
documentation from the chained ones. The documentation for all
properties is now in Help/prop_*/*.rst files.
We now need only the Usage formatter to support command-line options
that print basic usage, and the supporting indented=>preformatted markup
processor to support CMake message formatting. Drop all other
documentation formatters and move the remaining code up into the top
cmDocumentationFormatter class.
These checks want to know if named target properties are builtin, which
is now known by checking the Help/prop_tgt directory. (Previously the
check could be confused by a define_property call in the project.)
Install the Help directory next to Modules to make it available in CMake
distributions. Use cmRST to read Help .rst documents and print them as
help output.
Add options
--help-manual-list
--help-manual
to list available manuals or print one of them. Implement the options
--help-commands
--help-modules
--help-policies
--help-properties
--help-variables
by mapping to the corresponding manual page. Implement the options
--help-command-list
--help-module-list
--help-policy-list
--help-property-list
--help-variable-list
by globbing the available Help .rst documents of the corresponding type
and reading their titles. Implement the options
--help-command
--help-module
--help-policy
--help-property
--help-variable
by globbing the matching Help .rst document(s) and printing them.
Create a cmRST class to perform just enough reStructuredText processing
to support display of Help documents in human-readable text format.
This will be used to implement --help-* command-line options.
Support directives "include", "replace", "parsed-literal", "toctree"
(Sphinx), and "cmake-module" (CMake Sphinx Extension to scan .cmake
modules). Support inline CMake Sphinx Domain roles to convert
cross-references to corresponding title text. Support inline
substitutions defined by the "replace" directive, but keep it simple by
requiring replacements to be defined before use.
Add a CMakeLib "testRST" case to cover processing of supported
constructs and compare results against expected output.
We will no longer support full documentation generation from executables
and will instead generate documentation with other tools. Disable (with
a warning left behind) the command-line options:
--copyright
--help-compatcommands
--help-full
--help-html
--help-man
Drop supporting code. Drop manual sections generation from executables.
Remove internal documentation construction APIs. Drop unused sections
See Also, Author, Copyright, Compat Commands, Custom Modules.
Temporarily add a RST formatter to convert builtin documentation to .rst
source files. This will be removed shortly after we use it to convert
documentation.
Teach the RST formatter to:
* Output preformatted blocks as reStructuredText "::" literal blocks.
* Output option lists as bullet lists with option names enclosed in
reStructuredText ``literal`` quoting.
* Output individual documentation objects (commands, variables, etc.)
in separate .rst files organized in directories by type.
Replace references to cmVersion::GetCMakeVersion() in builtin
documentation with the literal placeholder "|release|" that will be
defined as a substitution later.
With our modern development workflow it is less likely a property will
be added to C++ code without documentation. This mode only existed to
support the DocTest which had very limited coverage of the properties
anyway.
Factor the CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR selection
out of CMakeLists.txt and into a Source/CMakeInstallDestinations.cmake
script. Load the script from the original location of the code.
Cache the destination values as empty strings so we know if the user
sets them explicitly. If not, then compute defaults based on the
platform and full CMake version string. By not caching the versioned
defaults, we can change them in a single build tree as the version
changes.
Remove duplication of the install destination defaults from the
bootstrap script. Cache empty defaults there too. Parse from the CMake
code the default values to report in the help output. Keep the CMake
code in a structured format to make this reliable.
Move logic to compute CMake_VERSION out of the top-level CMakeLists.txt
file to a dedicated Source/CMakeVersionCompute.cmake module and include
it from the original location. This will allow it to be re-used.

list(APPEND) has been able to append nothing since commit a06dcdba
(Allow LIST(APPEND) command to append nothing, 2008-01-16) but the
documentation still used to imply that at least one argument is
required.
The final location and name of a build-target is not determined
until generate-time. However, reading the LOCATION property from
a target is currently allowed at configure time. Apart from creating
possibly-erroneous results, this has an impact on the implementation
of cmake itself, and prevents some major cleanups from being made.
Disallow reading LOCATION from build-targets with a policy. Port some
existing uses of it in CMake itself to use the TARGET_FILE generator
expression.
The export-sets topic, merged in commit 49c7b649 (Merge topic
'export-sets', 2012-10-01) changed install(EXPORT) to allow
exporting targets whose dependents are exported separately
to different locations. Doing the same for export() was not
possible because the export() command was executed at
configure-time.
Now that export() is also executed at generate-time, make it
possible to export to multiple dependent export sets.
Make the API for adding targets string based so that it can easily
use cmGeneratorTarget.
Teach the cmIncludeCommand to generate the exported file at
configure-time instead if it is to be include()d.
The RunCMake.ExportWithoutLanguage test now needs a dummy header.h
file as expected error from export() is now reported after the
missing file error.
This is better than the cmCommand, because the lifetime of that is
not as useful, and it is only used to report an error anyway.
In the next commit, the cmExportBuildFileGenerator will outlive the
cmCommand.
Compilers for languages other than C and C++ on OS X may not understand
the -F framework search flag. Create a new platform information
variable CMAKE_<LANG>_FRAMEWORK_SEARCH_FLAG to hold the flag, and set it
for C and CXX lanugages in the Platform/Darwin module.

Add an unset() command option to remove a variable from the calling
scope, just like the set() command's PARENT_SCOPE option. Teach the
Unset test to cover such cases.
CMake is aware of the policy's NEW behavior and the AppleClang compiler
id. Set the policy to NEW explicitly to avoid the warning and get the
NEW behavior.
Also teach the RunCMake test infrastructure to build tests with
-DCMAKE_POLICY_DEFAULT_CMP0025=NEW to avoid the policy warning
in test output that must match specific regular expressions.
The parent commit introduced a separate "AppleClang" compiler id for
Apple's Clang distribution. Add a policy in order to support projects
that expect this compiler's id to be just "Clang". When the policy is
OLD or not set, map AppleClang back to Clang. Continue to use the
AppleClang id internally while enabling the language, but set the
CMAKE_<LANG>_COMPILER_ID after project() or enable_language() to the
compatible value for use by project code.
Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.
Currently, export() is executed at configure-time.
One problem with this is that certain exported properties like
the link interface may not be complete at the point the export() is
encountered leading to an incorrect or incomplete exported
representation. Additionally, the generated IMPORTED_LOCATION
property may even be incorrect if commands following the export()
have an effect on it.
Another problem is that it requires the C++ implementation of cmake
to be capable of computing the exported information at configure time.
This is a limitation on the cleanup and maintenance of the code. At
some point in the future, this limitation will be dropped and more
implementation will be moved from cmTarget to cmGeneratorTarget.
This target type only contains INTERFACE_* properties, so it can be
used as a structural node. The target-specific commands enforce
that they may only be used with the INTERFACE keyword when used
with INTERFACE_LIBRARY targets. The old-style target properties
matching LINK_INTERFACE_LIBRARIES_<CONFIG> are always ignored for
this target type.
The name of the INTERFACE_LIBRARY must match a validity generator
expression. The validity is similar to that of an ALIAS target,
but with the additional restriction that it may not contain
double colons. Double colons will carry the meaning of IMPORTED
or ALIAS targets in CMake 2.8.13.
An ALIAS target may be created for an INTERFACE library.
At this point it can not be exported and does not appear in the
buildsystem and project files are not created for them. That may
be added as a feature in a later commit.
The generators need some changes to handle the INTERFACE_LIBRARY
targets returned by cmComputeLinkInterface::GetItems. The Ninja
generator does not use that API, so it doesn't require changes
related to that.
