The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
Enable languages only in the individual test case. Enable the test
everywhere except Visual Studio generators (which do not implement the
properties) and just set fake flags as needed to activate relevant code
paths. Drop unneeded CMAKE_SUPPRESS_REGENERATION which seems to have
been copied from an unrelated test when this test was created.
Add an ExternalData_NO_SYMLINKS to enable use of copies instead of
symlinks to populate the real data files behind a DATA{} reference.
This will be useful on UNIX-like systems when the underlying filesystem
does not actually support symbolic links.

The 'ctest --launch' command must be placed before the IWYU launcher on
the compiler command line. Extend the RunCMake.IncludeWhatYouUse test
to cover this case. The Ninja generator already does it correctly.
This reverts commit f85db2f323.
Discussion by the QtCreator community at
https://bugreports.qt.io/browse/QTCREATORBUG-13695
raises concerns about this particular approach to working with CMake
projects using QtCreator. Also, the functionality and design of the QBS
extra generator was never discussed on the CMake mailing list or with
QtCreator developers. There may be better ways to make the two tools
work together.
In order to avoid committing to long-term support of this generator
prior to such discussion taking place, revert it from CMake for now.
We may restore this or use an alternative design based on results of
such discussion.
Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

The lexical scope counting added by commit v3.2.0-rc1~332^2~1 (Track
nested loop levels in CMake language with a stack of counters,

unclosed scopes. Teach the error handler to pop the lexical scope it
reports as unclosed. Re-order the lexical scope RAII object to be
inside the variable scope RAII object scope so that the lexical scope
is fully closed before we check assertions about variable scopes.

d430cb7c Tests: Fix failures when running under the default install prefix (#15566)
332ee3e3 Tests: Fix CheckSourceTree test when build is under source (#15566)
Fix test cases whose behavior differs when their source or build tree is
under CMAKE_INSTALL_PREFIX by setting an install prefix under the build
tree. Otherwise they may fail when run under the default install prefix
(e.g. /usr/local).
Since the build tree will populate content under the source tree
the test cannot reliably check that the source tree is pristine.
Simply skip most of the test in this case.
CPack DEB and RPM generators were not used for some tests because
CPACK_BINARY_DEB and CPACK_BINARY_RPM variable were not set. Fix this,
simplify generator selection in CTEST_RUN_CPackComponentsForAll, and fix
bugs that were detected after tests were run.
Use the KWSys Process "MergeOutput" option to give the child process
the same pipe (or file) for both stdout and stderr. This allows
natural merging of stdout and stderr together instead of merging
on arbitrary buffered read boundaries as before.
The VSExcludeFromDefaultBuild have not been enabled on VS >= 10 since
commit v3.0.0-rc1~260^2~9 (Tests: Simplify VSExcludeFromDefaultBuild
configuration, 2013-11-14). Since commit v3.0.0-rc1~260^2~2 (VS: Add
CMAKE_VS_(DEVENV|MSBUILD|MSDEV)_COMMAND variables, 2013-12-04) we can
simply check the CMAKE_VS_DEVENV_COMMAND variable for a devenv tool
to use for the test.
This reverts commit 242c3966 (add_custom_command: Diagnose
MAIN_DEPENDENCY limitation, 2015-03-09) and the follow up commit
b372a99a (UseSWIG: Do not use MAIN_DEPENDENCY on custom commands,
2015-03-26).
I misdiagnosed the underlying issue that prompted creation of policy CMP0057.
The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
