Expect cxx_variadic_templates to implement N2555.
N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.
Record the availability of this feature for GNU 4.8 on (UNIX AND
NOT APPLE) only. In the future, availability can be recorded for
earlier GNU, for other platforms and for other compilers. Initially
the affected configurations are as restricted as possible to allow
for easy testing while extending the features vector in only one
dimension.
The error message when using the set_property API directly is not
very good, but follow up commits will provide origin debugging of
the property and a target_compile_features command which will
provide a configure-time backtrace when possible.
Add a feature test using the compiler macros and the preprocessor to
determine available features.
Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features
known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable
containing all features known to CMake. Add language standard specific
variables for internal use to determine the standard-specific compile
flags to use.
This will be extended to other languages in the future. Follow-up
commits will add features which will be recorded by the feature test.
QT4_CREATE_MOC_COMMAND is given a moc_flags argument that contains the
COMPILE_DEFINITIONS and a potentially large list of include directories.
Since it is a macro, the ${moc_flags} reference is replaced with this
content and sent through cmMakefile::ExpandVariablesInString (EVIS).
Since commit v3.0.0-rc1~138^2 (Qt4: Use generator expression in
COMPILE_DEFINITIONS, 2014-01-13) the COMPILE_DEFINITIONS value contains
a '$' so the EVIS fast-path is no longer used. Instead the full
cmCommandArgumentParserHelper is now used on the large input, which is
very slow (since it was originally created for hand-written code).
Change QT4_CREATE_MOC_COMMAND to a function instead of a macro to avoid
passing large content through EVIS. This makes it significantly faster.
* Remove Watcom linker caseexact options already defined in system
definition.
* Use win_dll system for SHARED_LIBRARY and SHARED_MODULE.
* Use explicit target definition -bt=.. option for proper initialization

* Reorganize compiler options to global options and configuration
specific options
* Use option to optimize out stack checking code for release version
When adding a new external project, the "all" target will depend on
this.
This option allows one to add an external project will not be executed
when the "all" target is executed.
The reason for this is that an external project could be useful, for
example, only for running tests, and therefore not necessary during
the build.
When adding a new step using ExternalProject_Add_Step, the main target
will depend on this step.
This option allows one to add a step that will not be executed when the
main target for the external project is executed.
ExternalProject handles git remote branches by commit hash. Due to
this, the git repository ends in detached states, and local commits
are discarded.
Use "git rebase" for remote branches instead of "git checkout". If
there are uncommitted changes, use "git stash save/pop" to save changes
and restore them after the rebase. If any of these operations fails,
try to restore the original status and exit with a fatal error, asking
the user to resolve the conflicts manually.
This also makes the behaviour of ExternalProject using git more similar
to the svn version, and probably more likely to what the user expects
by setting GIT_TAG to a branch.
Previously the GTEST_ADD_TESTS function would miss parameterized tests
because it only considered TEST and TEST_F. Add TEST_P to the list of
considered tests and will run all instantiations of this parameterized
test together.
This is perhaps not as correct as searching for all instantiations of
this parameterized test and separating those into separate runs, but
this will at least run tests that were previously missing.

Fixes issues #14812 and #14813 where find_package(OpenMP QUIET) and
find_package(Qt4 QUIET) would still print out messages when calling
check*() functions.
Also a partial fix for #14445 where building CMake

and warnings come out of FindQt4.cmake.
Drop the CMAKE_NO_QUOTED_OBJECTS internal variable from the Makefile
generators. The underlying problem is with the Watcom linker, not with
WMake. The Watcom linker wants object files to be single-quoted. Add
<LINK-RULE>_USE_WATCOM_QUOTE platform information variables to tell the
generators to use Watcom-style single quotes for object files on link
lines.
On Windows, Watcom uses the GetCommandLine API to get the original
command-line string and do custom parsing that expects single quotes.
On POSIX systems, Watcom approximates the original command line by
joining all argv[] entries separated by a single space. Therefore we
need to double-quote the single-quoted arguments so that the shell does
not consume them and they are available for the parser to see.

Since commit v2.8.12~327^2 (Qt4Macros: Allow specifying a TARGET
in invokations of macros., 2013-02-26), a parameters file is
populated with moc arguments at generate-time.
When the compile definitions or include directories change, the
parameters file is updated but moc is not re-run in response.
Fix that by making the moc invocation depend on the parameters file.

Objective C sources should be compiled with the C compiler, not C++.
The Xcode generator correctly classifies ".m" sources already. The
cmSystemTools::GetFileFormat method was fixed by commit v2.8.0~1782 (fix
for 7045, use gcc for .m, 2008-08-19) but it is not used by any of the
generator since commit v2.4.0~2819 (major changes to support addition of
languages, 2004-09-22).
Fix the CMAKE_<LANG>_SOURCE_FILE_EXTENSIONS table entries so that
cmGlobalGenerator::GetLanguageFromExtension tells the Makefile, Ninja,
and VS IDE generators to compile ".m" sources as C. This makes behavior
consistent on all generators.

Use CMAKE_PREFIX_PATH, CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH
cache and environment variables to extend PKG_CONFIG_PATH before calling
pkg-config.
In each of the path in these variables it searches for lib/pkgconfig.
Then, depending on the system, it searches for
lib/${CMAKE_LIBRARY_ARCHITECTURE}/pkgconfig (debian) or for
lib64/pkgconfig (other 64 bit unixes). If any of these path is found,
it is appended to the PKG_CONFIG_PATH enviromnent variable.
Add two new arguments to the pkg_check_module and pkg_search_module
macro, NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH. The new signature
are therefore:
pkg_check_modules(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
pkg_search_module(<PREFIX> [REQUIRED] [QUIET]
[NO_CMAKE_PATH] [NO_CMAKE_ENVIRONMENT_PATH]
<MODULE> [<MODULE>]*)
By default, if CMAKE_MINIMUM_REQUIRED_VERSION is 3.1 or later (in
order to keep compatibility with the previous behavior), or if
PKG_CONFIG_USE_CMAKE_PREFIX_PATH is set, the CMAKE_PREFIX_PATH,
CMAKE_FRAMEWORK_PATH, and CMAKE_APPBUNDLE_PATH cache and environment
variables will be added to pkgconfig search path.
The NO_CMAKE_PATH and NO_CMAKE_ENVIRONMENT_PATH arguments disable this
behavior for the cache variables and the environment variables,
respectively, similarly to the find_package() command.
This example now works without need to enable C language:
cmake_minimum_required(VERSION x.x.x)
project(foo CXX)
include(CheckTypeSize)
check_type_size("short" SIZEOF_SHORT LANGUAGE CXX)
Fixes#14056
Add a CPACK_DEBIAN_COMPRESSION_TYPE option to set the compression type.
Default to 'gzip' to preserve existing behavior. Use "cmake -E tar"

Test the first argument directly for matching 'EXACT'. The error
check in its previous position was incorrect and would only trigger
with a version of '0' or similar.
During cross-compiling the toolchain file may use CMakeForceCompiler to
force a compiler setting. When using the Xcode generator try to convert
it to a full path by searching the PATH as is done for the Makefile
generators.

If a package is requested with an EXACT version, that doesn't imply
that dependencies must be found EXACTly too.
Extend the macro to allow specifying that a dependency must be found
by EXACT version instead.
Work around the command-line-length limit by using an @linklibs.rsp
response file to pass the flags for link libraries. This allows
very long lists of libraries to be used in addition to the existing
support for passing object files via response file.

The parent commit taught FindPythonLibs to try to find PythonInterp
unconditionally. Some projects may want the libraries of a specific
version even when the corresponding interpreter is not available. Drop
the internal use of FindPythonInterp and just use the versions from it
if it happens to have been found by the project first. That will allow
projects to get a consistent version when they want both but not
otherwise force them to find the interpreter.
In InstallRequiredSystemLibraries the version number for RTDLL can be
calculated from the compiler version. This will support current and
future OW versions without updating the module again.
For example it is now possible to do:
feature_summary(WHAT ENABLED_FEATURES
DISABLED_FEATURES)
That produces an output like:
--
-- The following features have been enabled:
* Feature1
* Feature2
-- The following features have been disabled:
* Feature2
Skipping the lists that are empty.
Without this patch this would require to do:
message(STATUS "")
feature_summary(WHAT ENABLED_FEATURES
DESCRIPTION "The following features have been enabled:")
feature_summary(WHAT DISABLED_FEATURES
DESCRIPTION "The following features have been disabled:")
And empty lists would not be skipped.
The behaviour when WHAT has a single argument (ALL or any option) is
unchanged.
When possible, get consistent version of the Python interpreter, headers path,
and library.
Now find_package(PythonLibs) internally calls find_package(PythonInterp
QUIET) and uses the resulting PYTHON_VERSION_MAJOR and
PYTHON_VERSION_MINOR to prefer these versions when looking for the
header path and library. The Python_ADDITIONAL_VERSIONS variable has
priority over the interpreter version.

Create each DLL import library by passing "option implib=..." to the
linker for its SHARED library. This works even when there are no
symbols to be exported. Leave the option out for MODULE libraries
because we do not need an import library for them. For executables,
retain the separate invocation of wlib because we want an import
library only when the ENABLE_EXPORTS property is set, and in that
case the project should provide symbols.

Now it only links with the Qt libraries specified by the user,
instead of automatically including all dependencies.
Fixes#14750 and thanks to Orion Poplawski.
Since commit v2.8.12~437^2~2 (VS: Separate compiler and linker PDB files
2013-04-05) we no longer set /Fd with the PDB_NAME or PDB_OUTPUT_DIRECTORY
properties. Those properties now exclusively handle linker PDB files.
Since STATIC libraries do not link their compiler PDB file becomes more
important. Add new target properties "COMPILE_PDB_NAME[_<CONFIG>]" and
"COMPILE_PDB_OUTPUT_DIRECTORY[_<CONFIG>]" to specify the compiler PDB
file location and pass the value to the MSVC /Fd option.
If there is no ARGV1, that is fine; version will be made empty, and no
version will be passed to find_package().
This is relevant when find_dependency is invoked multiple times,
sometimes with a version specified and sometimes without.
find_dependency(dep1 3.4)
find_dependency(dep2) # version still set to 3.4.
Teach ExternalProject_Add a new BUILD_ALWAYS option to skip using
the build step stamp file and execute the step on every build.
Extend the BuildDepends test with a case to cover this option.
When building boost with an alternate namespace the libraries generated
will have a different naming convention. This is often done to ensure
no symbol conflicts with external libraries built against a different
version of boost. If the namespace used is "myprivateboost::" instead
of "boost::" then the libraries built will be named myprivateboost_foo
instead of boost_foo. Add an option to specify a custom namespace used
to alter the library names that get searched for.
Create platform information modules Platform/Darwin-Intel-(C|CXX).cmake
and helper module Platform/Darwin-Intel.cmake. Teach existing module
Platform/Darwin-Intel-Fortran.cmake to use the helper too. Move
information from Platform/Darwin-icc.cmake into these files and drop
information already in Platform/Darwin.cmake to avoid duplication.
Some distributions place boost_mpi next to the MPI libraries against
which it was built instead of next to the other Boost libraries. If
find_package(MPI) has already been run prior to find_package(Boost) then
MPI_CXX_LIBRARIES or MPI_C_LIBRARIES may be set to the location of the
MPI libraries. Teach FindBoost.cmake to look there for boost_mpi and
boost_mpi_python after looking next to the other Boost libraries but
not consider the location to be Boost_LIBRARY_DIR.
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.
In commit v2.8.5~176^2~2 (FindOpenSSL: We should only use hints to find
OpenSSL, 2011-03-28) values for HINTS and PATHS of find_* calls were
computed everywhere but only used on Windows. Use them everywhere.
