Add a cmTarget::CompileInfo struct to hold per-configuration information
about the compilation settings in a target. This is different than
cmTarget::OutputInfo because it applies to any targets that can compile
sources even if they do not link or archive.
Implement a Visitor to hold the sequence of source file tests
for populating outputs. Use VS 6 and 7 workaround from Brad
King for lack of partial template specialization and function
template specialization capabilities.
This will make it possible to use context dependent generator
expressions to determine the sources of a target.
Replace calls to GetLinkInformation with calls to a method to get only
the target closure, not the link languages etc. The replaced calls
are used while evaluating generator expressions only. This makes
transitive generator expression evaluation independent from
the languages of a target. In a follow-up topic, it will be possible
to make the languages depend on generator expression evaluation, via
evaluation of the SOURCES and INTERFACE_SOURCES target properties.
Because the order of entries is not the same as the final link line,
the order of debug output is different in the RunCMake.CompatibleInterface
test, because the BOOL_PROP7 target property is evaluated first. Adjust
the test to account for that new order.
For the OLD CMP0022 behavior, we need to treat the implementation
as the interface when computing the interface libraries. Make it
possible to do that without computing the link languages by adding
a new GetLinkImplementationLibraries method. Extend the existing
GetLinkImplementation method to populate the languages if the
libraries have already been computed and cached.
Change GetTransitivePropertyTargets to invoke GetLinkInterfaceLibraries
instead of GetLinkInterface. This is key, as it is a method called
by cmGeneratorExpressionEvaluator.
Change the cmGeneratorExpressionEvaluator to invoke
GetLinkImplementationLibraries instead of GetLinkImplementation.
When evaluating the SOURCES property, we will need to be able to access
the link libraries without accessing the link languages, as the languages
depend on the SOURCES.
Arrange the logic so that the part which deals with libraries only is
at the top. In a follow-up commit, this will be split into two methods.
Ensure that the explanatory CMP0022 comment is only present in one
location.
The callers already skip non-targets, so unify the target search.
Change supporting functions to accept a container of targets instead
of strings where possible.
In a follow-up, the list of sources will become dependent on
the config, so check for existence in cmTarget::GetSourceFiles
instead of up-front with cmGlobalGenerator::CheckTargets().
6e89c8a5 install: Support generator expressions in FILES and PROGRAMS mode
f11f7b34 cmInstallFilesGenerator: Add reference to calling cmMakefile
e190236c Help: Format install() command documentation
Teach the install(FILES) and install(PROGRAMS) commands to evaluate

Extend the ExportImport test to cover installation cases involving
generator expressions.
Add a Makefile member to the cmInstallFilesGenerator class and
populate it on construction. This will be useful in a following
change to evaluate generator expressions with proper context.
The char-by-char parsing causes lots of reallocations which shouldn't be
necessary. To improve this, fast-path strings without a semicolon,
reserve space in the result, and insert into the result in chunks.
Optimize cmGeneratorExpressionLexer::Tokenize to use a switch statement.
The many dereferences of the input pointer were expensive. Also remove
excess pointer arithmetic.
Historically CMake used three version components for the feature level.
We released new features while incrementing only the third version
component. Since commit v2.8.2~105^2~4 (New version scheme to support
branchy workflow, 2010-04-23) we used the fourth version component for
bug-fix releases and the development date:
<major>.<minor>.<patch>[.<tweak>][-rc<n>] = Release
<major>.<minor>.<patch>.<date>[-<id>] = Development
This solidified use of three components for the feature level, and was
necessary to continue releasing 2.x versions because:
* Some existing projects performed floating-point comparisons of
${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION} to 2.x numbers
so ``x`` could never be higher than 9.
* Version 2.9.<date> was used briefly in post-2.8.0 development in
CVS prior to the transition to Git, so using it in releases may
have caused confusion.
Now that we are moving to 3.x versions, these two restrictions go away.
Therefore we now change to use only two components for the feature
level and use the scheme:
<major>.<minor>.<patch>[-rc<n>] = Release
<major>.<minor>.<date>[-<id>] = Development
The cmGeneratorExpression is used here, but the header for it is not
in the include heirarchy. This would be a compile error if the file
were compiled as a standalone translation unit, but it is instead
used in a mini-unity-build by inclusion in cmCommands.cxx. The header
for cmGeneratorExpression happens to be included first, so the
compilation works fine.
IDEs do not know this however, and flag the use as an error.
Several CMake operations need to replace files in rapid succession.
This commonly fails on Windows due to filesystem lock behavior so
we have retry loops. No matter how many times we retry or how long
we delay there will inevitably be someone with an environment that
needs more. Make the retry count and delay configurable in the
Windows Registry keys:
{HKCU,HKLM}/Software/Kitware/CMake/Config
in DWORD values
FilesystemRetryCount = Number of tries
FilesystemRetryDelay = Delay in milliseconds between tries
Leave the feature undocumented for now to see how it goes.
9bcc1b21 Export: Fix internal CMake version test logic
d2059d25 cmVersion: Fix CMake_VERSION_ENCODE for date in patch level
28805109 cmStandardIncludes: Include cmIML/INT.h for portable integer types
Fix the internal DEVEL_CMAKE_VERSION macro to use CMake_VERSION_ENCODE
to compare version component-wise. Otherwise an old invocation of the
macro may be tricked into using the current version when the requested
major version is smaller than the current version but the requested
minor version is larger. It should use the requested (old) version in
that case.
Use a uint64_t to store encoded version numbers so we have plenty of
bits available. Encode with room for up to 1000 minor releases between
major releases and to encode dates until the year 10000 in the patch
level. This is necessary because CMake development versions prior to
release 2.8.0 used the date in the patch level, and this practice may be
restored after the 3.0 release.
In CMakeGraphVizOptions.cmake, allow the options GRAPHVIZ_GENERATE_PER_TARGET
and GRAPHVIZ_GENERATE_DEPENDERS to enable the generation of per target graphs
and subgraphs respectively. Both options are TRUE per default to maintain
current behavior.
This is a hot-fix for the bug. It seems like a good idea to generally
reform the generator to care about targets instead of directories,
but this patch at least makes the reported error go away.
Define the list of commands in the CMakeLists.txt file. List the
sources in the CMakeLib target, but mark them as HEADER_FILE_ONLY.
This has the effect that IDEs will show the files, though they
will not be built again.
Add a cmCommandsForBootstrap.cxx file for bootstrapping purposes.
Rename the cmExportLibraryDependencies file to match the common
pattern.
The qtx_add_resources() macro adds the resource file to the output list
to maintain file-level dependencies. Having the qrc file in a target
sources is a precondition for AUTORCC to function.
When processing the source files of a target, only add the generated
qrc_<file>.cpp to the target sources if AUTORCC is ON. This avoids
pre-porting conflict with the macro.

Since commit v2.8.2~105^2~2 (Teach CMake Policies about tweak version
component, 2010-04-23), cmPolicies has known how to handle a policy
introduced in a tweak version. This was done back when we introduced
policies with the current development date version and later updated it
to the release version. Now we always introduce policies using the next
expected release version and explicitly set the policy to test the NEW
behavior.
CMake Policies (or any other features) should never be introduced in a
tweak (bugfix) release, so drop the infrastructure that allows this.
Set a global property in the find_package implementation. Track and
reset that property in the find_dependency macro. Read the property
in FeatureSummary when determining whether to print output.
This means that packages which are found only as dependencies are not
listed by FeatureSummary, but if a project uses find_package elsewhere
directly, then it will be listed by FeatureSummary.

Avoid using the moc from Qt 5 with Qt 4 based targets. Moc generates
a version check to ensure that such generated code does not compile.
The Qt4And5Automoc unit test should have been testing this, but it
was not because the test was broken. In that unit test, moc was run
on trivial files which have no significant content, and in particular
no Q_OBJECT macro. Therefore moc was generating empty files which
do not even contain the version check. Fix this by generating files
for input to moc at cmake time.

Images and xib files must have 'lastKnownFileType' attribute to be

Most callers already have a std::string, on which they called c_str() to pass it

Direct users of IMPORTED targets treat INTERFACE_INCLUDE_DIRECTORIES
as SYSTEM, after commit a63fcbcb (Always consider includes from IMPORTED
targets to be SYSTEM., 2013-08-29). It was intended that transitive
use of an IMPORTED target would have the same behavior, but that
did not work. The implementation processed only direct dependencies
in cmTarget::FinalizeSystemIncludeDirectories.
Implement transitive evaluation of dependencies by traversing the
link interface of each target in the link implementation.
The error messages were incorrect (reporting that the expression
requires one or two parameters), and repeated. Remove the now-unused
ZeroOrMoreParameters enum value.
There is no need to allow EXCLUDE_* properties, because an
INTERFACE_LIBRARY has no direct build output.
IMPORTED_LINK_INTERFACE_LANGUAGES are relevant only to static
libraries.
VERSION is relevant only to the filename of direct build outputs,
which INTERFACE_LIBRARY does not have.
If the dependent target sets the property to boolean false, ensure
that that appears in the debug report. Previously, the report
output contained whether the property was consistent among dependencies,
displaying 'TRUE', instead of the content of the property, which may
be 'FALSE'.
Return a std::pair from the consistentProperty method. This makes
it possible to make the return value for string types easier to
reason about. The return value of consistentProperty was previously
set to an empty static string to emulate a 'true' value for the caller
in commit 816b4a8a (cmTarget: Make consistentProperty
return consistent content., 2013-10-22). The pair makes the
consistency result properly typed.
Don't refer to 'both', but a 'mixture'. List all compatible interface
property types possible.
Add another test for a mixture of three compatibilities.
The include_directories() and add_compile_options() commands
should not append to the corresponding target property for IMPORTED
targets. This is already the case for add_definitions().
The modern way to create configuration dependent content is using
generator expressions in the main export file. The only non-deprecated
property still generated in the configuration-specific files are
IMPORTED_LOCATION_<CONFIG>
INTERFACE_LIBRARY targets have no location, and no need for those
files.
The next version is 3.0.0, not 2.8.13.
The version generated in the export file should be updated in
the release branch in both cmExportInstallFileGenerator and
cmExportBuildFileGenerator.

8bd6cf0 kate: the prev_target is not used by kate
The <OBJECT_DIR> placeholder is supposed to be the base intermediate
files directory for the current target. This is how it gets replaced
during link line generation. However, during compile line generation
we replace it with the directory containing the current object file
which may be a subdirectory. Fix replacement of <OBJECT_DIR> in the
generated compile lines to be the base intermediate files directory.
This was expoxed by commit 42ba1b08 (VS: Separate compiler and linker
PDB files, 2013-04-05) when we added a "/Fd<OBJECT_DIR>/" flag to the
MSVC compile line in order to match the VS IDE default compiler program
database location in the intermediate files directory. For source files
in a subdirectory relative to the current target this caused the wrong
location to be used for the compiler program database. This becomes
particularly important when using precompiled headers.
While at it, use the cmTarget::GetSupportDirectory method to compute the
intermediate files directory for the current target instead of repeating
the logic in a few places.
With this patch, cmake now puts the MachO64 bit

of install(TARGETS ... EXPORT foo). This makes maintenance of targets
exported to both the build tree and install tree trivial.
The first regression resulted in endless looping due to unrun test
dependencies. The second regression prioritized all tests with dependencies
in serial test runs.
Populate a separate vector of files and append them separately. This

The parent commit changed the AutogensType::value_type to be
"std::pair<cmQtAutoGenerators,cmTarget const*>" but our std::make_pair
call returns "std::pair<cmQtAutoGenerators,cmTarget*>". Construct the

The properties object has just been created, so is always empty,
which means the if block is never entered. The following lines do
not have any effect because an INTERFACE library has no LOCATION.
At the end, no code is generated for INTERFACE libraries in
config-specific exported files, so skip them early.
Existing single-parameter expressions work due to special casing
which assumes that if there is only one parameter, and the node
accepts arbitrary content, then the result is the input.
This is true for the existing expressions matching that
pattern - namely the "1" and "TARGET_NAME" expressions. However,
the LOWER_CASE, and UPPER_CASE expressions should also accept
arbitrary content, and in their case, the result is not the input.
Refactor the cmGeneratorExpressionEvaluator to allow that extension.
Actually evaluate the "1" and "0" nodes.
Added a new variable CPACK_WIX_PATCH_FILE that users can point at an
XML patch file. Fragments defined within the patch file will be inserted
at supported insertion points (currently Component, File and Directory).
As we're iterating over IMPORTED targets now, handle them in
the loop body. The existing behavior is harmless because generally
nothing is done anyway for IMPORTED targets in these code paths,
because they do not have sources for example.
Commit b04f3b9a (Create make rules for INTERFACE_LIBRARY
targets., 2013-08-21) extended the makefile generator to create
build targets for INTERFACE_LIBRARY targets. No other generators
were extended with this feature.
This conflicts with the feature of whitelisting of target properties
read from INTERFACE_LIBRARY targets. The INTERFACE_* properties
of the INTERFACE_LIBRARY may legitimately contain TARGET_PROPERTY
generator expressions for reading properties from the 'head target'.
The 'head target' would be the INTERFACE_LIBRARY itself when creating
the build rules for it, which means that non-whitelisted properties
would be read.
The INTERFACE_LIBRARY type does not have any LOCATION at all, so
return early from GetMappedConfig. GetMappedConfig is called from
two locations, one of which already pre-checks the INTERFACE_LIBRARY
case. Remove that pre-check and handle that case inside the method
instead.

On posix platforms return values are limited to a range from 0 to 255.
Cross compiling/linking with MSVC on linux/wine leads to a
misinterpretation of the return value 1090650113 of mt.exe.
Fix logic introduced by commit eeeeca10 (XCode: Support target folders
on XCode, 2011-02-20) to avoid duplicate subfolders. The problem was
that no slash was appended to the curr_tgt_folder string on the it !=
this->TargetGroup.end() path.
This was missing from commit c34968a9 (Port some of the generator
API to cmGeneratorTarget., 2012-10-10). The generator targets
stored with the cmMakefile include IMPORTED targets, unlike the
accessor for resgular targets. Before this patch, rules would
be generated for Qt5::Core for example, which result in broken
makefiles.
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.

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.

Rename cmSystemTools::FindExecutableDirectory to FindCMakeResources.
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/cmTarget.cxx by integrating the changes to
the internal copy constructor from both sides. Also resolve a logical
conflict by dropping the special case for INTERFACE_LIBRARY targets.
Since cmTarget::SetMakefile already forces CMP0022 to NEW for such
targets we need no special handling.
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.
