Due to MCST LCC compiler identification is now changed to LCC,
there should be a way for old projects to still identify it as GNU,
as it was before.
This commits adds the policy:
CMP0129: Compiler id for MCST LCC compilers is now LCC, not GNU.
This policy controls such a behavior.
OLD behaivior is to treat LCC as GNU, NEW is to treat is as LCC.
When using the Visual Studio generator for VS 10 or above,
offer this key to get the location of the MSBuild command
before the first `project()` or `enable_language()` command
has finished running.
This will be needed only by one of our own modules, so leave it
undocumented for now.
When both CMAKE_FIND_ROOT_PATH and CMAKE_PREFIX_PATH are set to
/opt/my_device_sysroot, cmFindCommon::RerootPaths would only look
for packages in /opt/my_device_sysroot/opt/my_device_sysroot
but would not try to look in /opt/my_device_sysroot.
Make sure to not reroot the prefix path in such a case.

The target properties `CUDA_SEPARABLE_COMPILATION` and `CUDA_PTX_COMPILATION`
now aren't mutually exclusive and can now be used together on the same
target.
Sources that are part of a unity build are normally not compiled
individually. However, the VS IDE allows a single source to be
compiled. This can also be achieved on the command line:
msbuild my.vcxproj ... -t:ClCompile -p:SelectedFiles=<src>
where `<src>` is the path in the vcxproj `ClCompile` entry.
In a target with precompiled headers, the source needs PCH settings to
support individual compilation even if the normal unity build does not.

Enabling `IMPORTED_NO_SYSTEM` on a target built within the project has
no effect on the build system, but it is still a useful way to set the
property on imported targets generated by `install(EXPORT)` and
`export()`.
Issue: #17364
Divert LCC compiler as a new one, instead of treating it as GNU.
Since old times, Elbrus C/C++/Fortran Compiler (LCC) by MCST has been
passing checks for GNU compilers, so it has been identified as GNU.
Now, with intent of seriously upstreaming its support, it has been
added as a separate LCC compiler, and its version displays not a
supported GCC version, but LCC version itself (e.g. LCC 1.25.19 instead
of GNU 7.3.0).
This commit adds its support for detection, and also converts basically
every check like 'is this compiler GNU?' to 'is this compiler GNU or
LCC?'. The only places where this check is untouched, is where it
regards other platforms where LCC is unavailable (primarily non-Linux),
and where it REALLY differs from GNU compiler.
Note: this transition may break software that are already ported to
Elbrus, but hardly relies that LCC will be detected as GNU; still such
software is not known.
"OS Elbrus" (OSL for short), a reference Linux distro for E2K (Elbrus)
platform may have broken dpkg-shlibdeps, that doesn't specify
dependencies correctly. In this case, the only reliable way is to
explicitly set dependencies of libc6 and lcc-libs, and then warn user
to let him know this list may be incomplete. This commit does that.
This fix has no effect on correctly working dpkg-shlibdeps, so when
this bug will be fixed in new versions of OSL, CPack will work as
expected with these distros.
There are several tests that run on systems that have rpm installed, but
they fail if there's no debugedit installed also. This commit makes
these tests being skipped in such case.
RunCMake/CommandLine has problems
when ran using language setting differeng from English. This is due to
test outputs being compared to English strings, which comparison
obviously fails if this language is set to, e.g. Russian. This commit
sets locale as "C" prior to running these tests, so messages while
testing are generated in correct language and do not fail checks
anymore.
Add an `IMPORTED_NO_SYSTEM` target property to specify this. When
enabled, do not treat the `INTERFACE_INCLUDE_DIRECTORIES` of an imported
target as `SYSTEM` include directories.
This is similar to the existing `NO_SYSTEM_FROM_IMPORTED` property, but
works from the consumed target rather than the consumer.

The OLD behaviors of all policies are deprecated, but only by
documentation. Add an explicit deprecation diagnostic for policies
introduced in CMake 3.15 and below to encourage projects to port
away from setting policies to OLD.
Revert commit 798c1c3192 (GNUInstallDirs: Comply with Debian Policy on
LIBEXECDIR, 2020-10-08, v3.19.0-rc1~11^2).
The Debian Policy builds upon FHS 3.0 and permits installing to
`/usr/libexec`. While Policy does grant an additional exception for
applications to use a single subdirectory of `/usr/lib/<triplet>`, this
is not meant to replace `/usr/libexec` as valid target.
Fixes: #22731
This case was added by commit e3ff7ced63 (file(INSTALL): Add
FOLLOW_SYMLINK_CHAIN argument, 2019-05-16, v3.15.0-rc1~103^2).
Skip it on Cygwin because it fails due to `foo/../` pairs being
flattened away in symlinks.

The minimum CMake version for Qt6 is 3.16, so all the calls to
cmake_minimum_required() are updated here to enforce that
minimum. This will avoid any CMake version-related warnings
from Qt.
Avoid hard-coding Qt5 where the tests could now be using
Qt5 or Qt6.
Fixes: #22188
The changes are part of CMP0128.
When the standard level is unset:
* Flags are added if extension mode doesn't match the compiler's default.
Previously logic only worked if LANG_EXTENSIONS was ON. Fixes#22224.
* The full flag is used. Previously CMAKE_LANG_EXTENSION_COMPILE_OPTION was
used. This was only supported for IAR.
Otherwise:
* Avoid adding flags if not necessary per the detected compiler defaults.
* Fixed check for when the requested standard is older. It now matches the
nearby comments.
I reworded the fallback comment as its logic was a bit difficult to wrap my
head around.
