Drop use of cmSystemTools::RunCommand. It used popen on UNIX
(equivalent to /bin/sh -c "$command") and direct CreateProcess calls on
Windows. Implement equivalent behavior using the KWSys Process library.

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.

...
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 a new command line argument to ctest. This allows users to

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.

Re-insert the semicolon which was removed during splitting.
Commit d777b8e7 (Genex: Allow relative paths in INSTALL_INTERFACE.,
2013-07-25) introduced the prefixItems method to allow relative paths
in the argument of the INSTALL_INTERFACE expression. That method was
buggy in that it did not re-introduce the semicolon separator in
the result.
This bug also affects paths which are already absolute in user code.
Some compilers try to simulate other compilers as a drop-in replacement
supporting all the same command-line options and predefined preprocessor
macros. In such cases it will be useful to have CMake load the compiler
information files for the simulated compiler instead of duplicating the
information. Teach CMakeDetermineCompilerId to extract the simulated
compiler id and version when the compiler id detection provides it.
Move the cmake::ExecuteCMakeCommand static method and all the static
methods it calls out of the 'cmake' class to a separate 'cmcmd' class.
Build the latter as part of the main cmake executable with cmakemain.cxx
and not in CMakeLib. Drop unused header includes from "cmake.cxx".
By moving this implementation out of cmake.cxx we avoid carrying it
around in all the executables that use class 'cmake'. It is needed only
for the main "cmake -E" functionality.
Xcode 2.1 through 4 supported $(CURRENT_ARCH) in a PBXFileReference
'path' value used in the "Link Binary with Libraries" build phase.
CMake uses this to reference object file locations on link lines to
bring in OBJECT library content. However, Xcode 5 now evaluates the
$(CURRENT_ARCH) reference in this context as "undefined_arch" so the
wrong path is given to the linker. There seems to be no alternative way
to produce an architecture-specific value in a PBXFileReference.
Fortunately Xcode 5 now also handles link dependencies for paths linked
through OTHER_LDFLAGS. For Xcode >= 5, move the OBJECT library object
file references from the link build phase to OTHER_LDFLAGS. We can
still show the object files in the source group listing in either case.
Xcode 5.0 now computes dependencies from files linked through
OTHER_LDFLAGS, so we no longer need the XCODE_DEPEND_HELPER hack to
re-link dependents when targets change.
In buggy code like
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
MAIN_DEPENDENCY ${CMAKE_CURRENT_SOURCE_DIR}/out.h.in
...)
add_custom_command(
OUTPUT ${CMAKE_CURRENT_BINARY_DIR}/out.h
...)
that has more than one rule to generate the same output CMake has always
used the first rule. However, since commit 2268c41a (Optimize custom
command full-path dependency lookup, 2013-08-06) we update the map from
output to cmSourceFile for every rule generating an output, effectively
keeping the last command instead of the first.
Fix this regression by checking for each map update if the output
already has an entry. If so, keep only the original entry. The VS 8
generator triggers this with a special case for generate.stamp rules
that differ between ZERO_CHECK and normal targets, so do not warn for
now. Leave a TODO comment for warning in the future.
Multiple libraries in a single buildsystem can be exported to multiple
export-sets.
If a library from one export set depends on a library from
another export set, the export logic generates a check in the targets
file to verify that the target in the other export set is found. That
check is executed at downstream-find_package-time.
However, a target may depend privately on a target in another export
set. In that case, the depend used to also be listed in the required
targets in the targets file. Change the export logic to ignore the
private link entries instead.
Resolve conflict in Source/cmTestGenerator.cxx by taking "their" side
(test-property-genex). It already accounts for the lower-case change in
"our" side (generate-modern-style).
The old-style add_test() call does not support generator expressions at
all. This also applies to the properties for the test, but it is not
mentioned at all.
This is useful for cases like:
add_test(NAME mytest COMMAND mydriver $<TARGET_FILE:myexe>)
set_tests_properties(mytest PROPERTIES
REQUIRED_FILES "$<TARGET_FILE:myexe>"
WORKING_DIRECTORY "${CMAKE_CURRENT_BINARY_DIR}/$<CONFIGURATION>"
)
In this example we require the actual test executable to exist to
run the test in addition to the test driver at argv[0]. Also the
$<CONFIGURATION> expression improves over \${CTEST_CONFIGURATION_TYPE}
because the latter is not normalized for case-sensitive filesystems.
Move property generation from GenerateScriptConfigs to separate copies
in GenerateOldStyle and GenerateScriptForConfig. This causes the
per-config tests generated for the add_test(NAME) signature to each get
their own test properties. This will allow us to later change the
property values based on the test configuration.
While at it, generate lower-case CMake code (e.g. set_tests_properties).

Teach cmListFileLexerDestroy to call cmListFileLexerSetToken with a NULL
token to free the token string buffer. Without this, if an error occurs
before the token cleanup happens when EOF is reached, then the token
string buffer may leak.
Only one argument is required. Also avoid using the same variable name twice in
the input list and follow the convention used elsewhere for optional arguments.
Similar incomplete generator expressions are already tested
in the GeneratorExpression unit test, but those are executed
with add_custom_target. The generator expressions in the include
directories are run through the preprocessor, whereas the ones
run through add_custom_target are not.
The version of Intel Fortran that actually uses 9.10 as a project format

We populate and maintain a vector of structs to keep track of
backtraces already, so no need to populate the Properties container
additionally.
For completeness, it is necessary to remove the condition for
populating the vector for only valid library names and generator
expressions. That condition is now determined when evaluating the
generator expressions.
Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake. The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing. However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
We have to also track input files to the configure command. In theory
the input to a configure command could it self be a file that is going
to be deleted later (output from a custom command or configure_file).
The feature needs access to all link libraries. In the future that
will only be possible to calculate at generate-time.
Even when the files were generated at configure time, they were
generated after user code in CMakeLists files were generated. No
policy is needed to handle manipulation of the files from CMake
code, because that was never possible.

This is necessary because custom commands and targets may create
custom files whose names are determined by generator expressions.
For example, clang should be using $<TARGET_FILE> and $<TARGET_FILE_DIR>
instead of reverse engineering the output file name:
http://thread.gmane.org/gmane.comp.compilers.clang.scm/80523
However, that can only be done when ADDITIONAL_MAKE_CLEAN_FILES
also accepts and evaluates generator expressions.
Similarly, KDE uses the LOCATION property where $<TARGET_FILE>
would also be better in KDE4_HANDLE_RPATH_FOR_EXECUTABLE but
also appends the result to ADDITIONAL_MAKE_CLEAN_FILES.
After this patch, both can be ported to generator expressions.
Commit 10a069b5 (Genex: Fix $<CONFIG> with IMPORTED targets and
multiple locations., 2013-07-15) changed the logic here to include
handling of the MAP_IMPORTED_CONFIG_<CONFIG> target property, but
it was buggy in several ways.
Uppercase the configs in all cases, and compare the mapped configs
with the parameter to the CONFIG genex, instead of with the key of
the mapping.
Ensure CMAKE_DATA_DIR, CMAKE_DOC_DIR, and CMAKE_MAN_DIR are always
relative paths in CMake code, and set defaults accordingly. Use the
install() command instead of install_files() and install_targets().
This is more modern and also avoids stripping of the first character
from user-specified destinations.
While at it, fix the default destinations reported in the bootstrap
help.

To fix this, each callback is now a separate entity completely and
doesn't rely on the command which spawned it at all.
An example CMakeLists.txt which demonstrates the issue (only displayed
in cmake-gui, so no tests can be written for it):
set(var 0)
variable_watch(var)
When removing a watch on a variable, using the operator [] on the
internal map will create an empty watch if the variable doesn't have any
existing watches. Rather than creating this empty structure in the map,
return if there isn't a watch on the variable already.
If a callback has the same data as another call, we don't want to delete
the old callback. This is because if the client_data is the same, it
might get deleted causing the new client_data to be bogus. Now, AddWatch
will return true if it will use the watch, false otherwise. Callers
should check the return value to know whether client_data was adopted by
the watch or not.
The client data is arbitrary and the callback may be called an
unspecified number of times, so the cmVariableWatch must be the one to
delete the client data in the end (if it is needed at all).
In the future CMake will introduce Lua-style long bracket syntax.
Warn about unquoted arguments that in the future will be treated
as opening long brackets.
Teach the RunCMake.Syntax test to cover such cases and ensure that the
warning appears.
Teach the lexer to return tokens for whitespace. Teach the parser to
tolerate the space tokens where whitespace is allowed. Also teach the
parser to diagnose and warn about cases of quoted arguments followed
immediately by another argument. This was accidentally allowed
previously, so we only warn.
Update the RunCMake.Syntax test case StringNoSpace expected stderr to
include the warnings.
Replace the boolean value that indicates whether an argument is unquoted
or quoted with a generalized enumeration of possible argument types.
For now "Quoted" and "Unquoted" remain the only types.
If a line inside a string ends in a backslash count the following
newline character as a line increment. Add a test covering this case to
verify that subsequent line numbers are correct.
The output file used for memory checker runs must be unique for every test run
in parallel, so simply make them unique for every test run. Simply use the test
index to avoid collisions.
Some generated cm*Lexer.h headers define preprocessor macros normally
provided by <stdint.h>. The latter is included indrectly by cmMakefile.h
since commit 2268c41a (Optimize custom command full-path dependency
lookup, 2013-08-06). Adjust the order to avoid redefinition warnings.

In the common case of custom command dependencies specified via full
path optimize the implementation of GetSourceFileWithOutput using a
(hash) map. This is significantly faster than the existing linear
search. In the non-full-path case fall back to the existing linear
suffix search.
Since we do not need the information about the target architecture
we can use the PlatformName only to specify the this information.
This also removes setting of the MSVC_*_ARCHITECTURE_ID variable
which is not required, because this variable gets set by the
compiler detection code in CMAKE_DETERMINE_COMPILER_ID_CHECK().
* The ALIAS name must match a validity regex.

* An ALIAS can be used with add_custom_command, add_custom_target,
and add_test in the same way regular targets can.
* The target of an ALIAS can be retrieved with the ALIASED_TARGET

Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake. The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing. However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
Teach cmMakefile::ConfigureFile to skip tracking files with "CMakeTmp"
in their path, just like cmCoreTryCompile::TryCompileCode does to
avoid adding dependencies on temporary source files. In the future
we will need a more general filter to avoid recording as CMake
outputs any files that do not exist at the end of generation.
The new feature of install(TARGETS ... INCLUDES DESTINATION) introduced
in commit 650e61f8 (Add a convenient way to add the includes install
dir to the INTERFACE., 2013-01-05) introduced this crash. If the
new feature is used with a target which has no
INTERFACE_INCLUDE_DIRECTORIES, a segfault occurred.
Commit 650e61f8 (Add a convenient way to add the includes install
dir to the INTERFACE., 2013-01-05) introduced an error case for
using the install(TARGETS) command with specified INCLUDES DESTINATION,
but no specified EXPORT set.
It is convenient to use a variable to set the various destinations
for different outputs (as KDE does), and some targets such as
executables are installed but not exported. This was triggering
the error case, but as it is a common case, remove the error.
Pass the original file handles to the native tool when using the
--use-stderr option in the build command. This enables the
usage of advanced terminal features like colored output.
This reverts commit 6187876dea.
It was actually possible before to have paths with spaces in them, the spaces
just need to be quoted. This way spaces will work as argument separators.
Ninja relies on the generator to produce paths that match up with the
paths used in the build.ninja file, which are spelled with backslashes.
Therefore, cmcldeps should canonicalize depfile paths to use backslashes
and relativize paths to the build directory.
GCC warns:
dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
on constructs like
*(sha_word64*)&var =
so use memcpy to perform such assignments instead.
First, it prevents a NULL dereference and second it reiterates that
targets without languages are not supported by CMake.
Add a RunCMake.ExportWithoutLanguage test exporting a library without a
languages.
Add a new signature to help populate INTERFACE_LINK_LIBRARIES and
LINK_LIBRARIES cleanly in a single call. Add policy CMP0023 to control
whether the keyword signatures can be mixed with uses of the plain
signatures on the same target.
Export the INCLUDES DESTINATION without appending to the
INTERFACE_INCLUDE_DIRECTORIES of the target itself. That way, a target
can be exported multiple times with different INCLUDES DESTINATION
without unintended cross-pollution of export sets.
It accepted an optional argument to test for equality, but no way
to get the linker language of a particular target.
TARGET_PROPERTY provides this flexibility and STREQUAL provides
the necessary API for equality test.
Extend the CompileDefinitions test to cover accessing the
property of another target.
We already document the variables CMAKE_<LANG>_FLAGS_{DEBUG, MINSIZEREL,
RELEASE, RELWITHDEBINFO}. However, CMAKE_<LANG>_FLAGS is not documented,
even though it's available (and useful).
On windows we had a subset of the paths as unix style and a subset as windows

This patch adds a comment above the block which protects

WiX provides a lot of functionality for installers that cannot be
supported (easily) in the default WIX.template.in file.
For most users, the default template should be fine. However if users
want to produce merge modules, include custom actions, etc, this new
option allows for a hook into how the wxs is produced.

The VS IDE sets the environment variable VS_UNICODE_OUTPUT when
executing build rules in order to tell MS tools to report output through
a back door instead of through stdout/stderr. Unset this variable so
that CMake can capture or properly redirect all output from processes it
runs even when running inside a VS IDE build environment.
This generalizes the special cases fixed by commit 80d045b0 (When
GetPrerequisites.cmake runs dumpbin while running inside the VS IDE...,
2008-05-01) and commit 44aff73d (ExternalProject: Avoid bleed-through
output when logging, 2011-01-06), so drop special handling of
VS_UNICODE_OUTPUT in those instances.
Unlike other target properties, this does not have a corresponding
non-INTERFACE variant.
This allows propagation of system attribute on include directories
from link dependents.
Drop the "vsProjectFile" argument from cmTarget::TraceDependencies. It
appears to be the modern equivalent to a hunk added in commit ba68f771
(...added new custom command support, 2003-06-03):
+ name = libName;
+ name += ".dsp.cmake";
+ srcFilesToProcess.push(name);
but was broken by refactoring at some point. The current behavior tries
to trace dependencies on a source file named the same as a target, which
makes no sense. Furthermore, in code of the form
add_executable(foo foo.c)
add_custom_command(OUTPUT "${somewhere}/foo" ... DEPENDS foo)
the "vsProjectFile" value "foo" matches source "${somewhere}/foo.rule"
generated to hold the custom command and causes the command to be added
to the "foo" target incorrectly.
Simply drop the incorrect source file trace and supporting logic.
Return early in cmake::ReportUndefinedPropertyAccesses if there is no
global generator instead of opening a file and leaking the descriptor.

When the COPY_FILE operation fails optionally capture the error message
with a COPY_FILE_ERROR option instead of reporting the error
immediately. This gives callers a chance to do something else or report
the error.
Teach the RunCMake.try_compile test to cover bad argument combinations
involving COPY_FILE_ERROR. Teach the TryCompile test to cover the case
of a COPY_FILE error message captured by COPY_FILE_ERROR.
If CMAKE_<lang>_FLAGS contains quotes or other CMake language characters
they must be escaped when written into the generated CMakeLists.txt file
so that the test project parses them properly.
Teach the TryCompile test to cover this case by adding a flag with
quotes into CMAKE_C_FLAGS during a C language try_compile.
Use constructs similar to those for COMPILE_OPTIONS. This is a little
different because there is a command to remove_definitions(), so
we can't populate the equivalent target property until generate-time
in cmGlobalGenerator.
Use preprocessor loops and add a unit test for the appropriate
policies. All policies whose value is recorded at target creation
time should be part of this list.
When CMake reports failure to configure a project, especially when the
toolchain does not initialize properly, the true reason may be clear
from reading the CMakeFiles/CMake(Output|Error).log files. Advise users
to look at these files if they exist when configuration fails.
Add RunCMake.Configure test to check that the log files are mentioned
when configuration fails.
We have two mappings for the "/MAP" flag. The first does not care
whether there is a value and activates the GenerateMapFile boolean
setting. The second takes a value and puts it in the MapFileName
setting. The latter must treat the ":" as part of the flag.
This is similar to commit 8ae66bf4 (Fix optionally-valued booleans in VS
10 flag table, 2009-10-23).
The wording "Commands in the file are processed immediately as if they
were written in place of the include command" sounds as if some kind of
macro replacement is performed. This is not accurate. Update the
wording to describe behavior of the included code in terms of the
variable access scope.
Always populate the INTERFACE_LINK_LIBRARIES for interface
entries. Don't populate the old interface properties
matching (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?
if CMP0022 is NEW.
Because the INTERFACE_LINK_LIBRARIES property is now populated by
the target_link_libraries when operating on a static library,
make an equivalent change which populates the property with
the same value when the old link_libraries() command is used. This
silences the policy warning in that case.
This property is generated only for targets which have recorded
policy CMP0022 as NEW, and a compatibility mode is added to
additionally export the old interfaces in that case too.
If the old interfaces are not exported, the generated export files
require CMake 2.8.12. Because the unit tests use a version which
is not yet called 2.8.12, temporarily require a lower version.
This property replaces the properties which
match (IMPORTED_)?LINK_INTERFACE_LIBRARIES(_<CONFIG>)?, and is enabled
for IMPORTED targets, and for non-IMPORTED targets only with a policy.
For static libraries, the INTERFACE_LINK_LIBRARIES property is
also used as the source of transitive usage requirements content.
Static libraries still require users to link to all entries in
their LINK_LIBRARIES, but usage requirements such as INCLUDE_DIRECTORIES
COMPILE_DEFINITIONS and COMPILE_OPTIONS can be restricted to only
certain interface libraries.
Because the INTERFACE_LINK_LIBRARIES property is populated unconditionally,
we need to compare the evaluated result of it with the link implementation
to determine whether to issue the policy warning for static libraries. For
shared libraries, the policy warning is issued if the contents of
the INTERFACE_LINK_LIBRARIES property differs from the contents of the
relevant config-specific old LINK_INTERFACE_LIBRARIES property.
CMake requires the top-level CMakeLists.txt to contain a direct call to
the project() command and will insert one if there is not. Document
this requirement since some authors have tried to use include() to load
a file calling the project command.
This was missing from commit 30962029 (Make targets depend on the
link interface of their dependees., 2012-12-26), which caused
only immeditate entries of the link interface to become target
depends.
Entries from the cmMakefile are processed and maintained similarly
to other include directories. The include_directories(SYSTEM)
signature affects all following targets, and all prior targets
in the same makefile.

88d27ad Add a test to expose a bug with add_custom_command and ninja.
When converting custom commands for the ninja build system we
need to make sure that any file dependencies that exist in the build
tree are converted to phony targets. This tells ninja that these
files might not exist when starting the build, but could be generated
during the build.
This is done by tracking all dependencies for custom command targets.
After all have been written out we remove all items from the set
that have been seen as a target, custom command output, an alias,
or a file in the source directory. Anything that is left is considered
to be a file that will be generated as a side effect of another
custom command.
To properly track the usage of dependencies that are generated at
compile time as the side effect of other build steps we need
to make the WriteBuild and WritePhonyBuild commands non static

In my project group we are using CMake to generate c++/cli winform
projects and I noticed the work done in commit 79ec7868 (VS: Add Windows
Forms Support, 2013-04-29) was in the right direction for solving some
of the problems we were facing.
The changes as submitted was breaking some functionality in our
projects, so I made some changes that fixes our problems and I believe
that it will also work for others.
* Resx files did not link correctly with the winform h-file so I added
the Resx configuration to the vcxproj file.
* I removed the functionality for setting <CLRSupport> true for the
project based on if an resx-file is pressent. This is preventing
us from using native cpp code. Also this do not address that some
projects will need to set other options like clr:pure, clr:safe.
This could be implemented as a cmake option, so it is possible to
specify exactly what is needed. Existing VSWindowsFormsResx Test
project is updated so it will be working with my changes.

Currently when a configured file is removed from the build directory,
running the build command will not regenerate the file. Now detect
this and will rerun cmake properly when a user issues the build
command.
AddCMakeDependFile and AddCMakeOutputFile both store as std::string
and all calling sites use std::string. So instead of creating more
temporary objects, lets just use std::strings.
Through use of libarchive internally we support .zip files as well as
.tar format. The ExternalProject module makes use of this feature.
Document support officially.
Expose the internal system information API to the CMake language. For
example, it is useful to see how much memory the system has available to
estimate an upper limit of tests that can run in parallel.
Each call to AddDefinition has overhead for variable watches and such.
Avoid extra calls when not needed.
This decreases the configure time for ParaView by 10 seconds on my
machine. Without the change about 1,000,000 set-to-empty calls were
being made. After the change it drops to about 100,000.
The SHA512_Update implementation accesses input data via 64-bit
integers. This requires alignment of the input buffer on some
architectures. Align our stack-allocated buffer for file content to
satisfy this requirement.
Describe explicitly the scope in which enable_language must be
invoked to handle all direct and indirect uses of a language.
While at it, re-word documentation of the OPTIONAL keyword to
avoid confusion over its partial implementation.
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.
