This was intended to be part of the initial MR (!6177), but accidentally went
missing when debugging nightly failures on less common systems. Noticed during
!6711 review as the comment about this behaviour didn't match the code.
Documentation for CMP0128 is updated to remove a false case and note the two
cases related to this.
Fixes#22224.
Single-config generators already support unity builds with per-config
sources because they compute sources using `CMAKE_BUILD_TYPE` as the
configuration. Each original source is either included in the unity
build source, or not.
Teach multi-config generators to compute the list of sources for
inclusion in unity builds using all configurations. Previously they
only used the empty string as the configuration. Each original source
may be included in some configurations, but not others. Use
preprocessor conditions to guard their inclusion when necessary.

Add link flags during the "device compile" step.
Enabled the relevant tests. The disable reasons regarding separable compilation
were outdated and the actual failure case was device link flags support.
This CPack generator was never documented, and has been deprecated since
commit 2ed00e8ef8 (CPack: Deprecate OSXX11 generator, 2020-01-31,
v3.17.0-rc1~45^2).
Issue: #20235
Generator expressions in a non-cross custom command's `COMMAND`
arguments are evaluated in the command config. Target-level
dependencies implied by `TARGET_FILE` must therefore be cross
dependencies. This is important to generate proper target-level
dependencies on the cross-config build statements for the target to
which the custom command is attached.
Fixes: #22855
The CTestTestCrash tries to force a crash by dereferencing a NULL
pointer. The oneAPI 2021.4 C compiler notices that the pointer and the
value fetched from the pointer are never used and optimizes away the
dereferencing of the NULL pointer, which prevents the crash, causing
the test to fail.
This change adds the `volatile` keyword the pointer to prevent the
compiler optimizing it away. Removing a reference to a `volatile`
variable is illegal because access to a `volatile` variable could have
side effects not observable by the compiler.

Previously the `CMAKE_GENERATOR_INSTANCE` value was used only to filter
the instances reported by the Visual Studio Installer tool. If the
specified install location is not known to the VS Installer, but the
user provided a `version=` field, check for the installation directly
on disk.

This only works due to some assumptions about how the `ENVIRONMENT`
property is processed. Comments have been added to notify anyone
modifying the behavior about where to look.

This makes `versionadded` and `versionchanged` directives show up in
`cmake --help-*` output instead of disappearing (and potentially making
empty sections).
Fixes: #22808
When appending or modifying to a variable that has not been modified
before, the iterator was not valid, but it was used to insert into the
map again. Instead, just use indexing into the map since we know it will
exist by the end of the function anyways.
Fixes: #22796
GCC mistakenly issues the pedantic warning "ISO C forbids conversion of
function pointer to object pointer type". With -pedantic-errors in the
compile flags, that diagnostic prevents check_symbol_exists() from
detecting function symbols.
The solution is to filter out -pedantic-errors (and -Werror, just to be
future proof) before invoking try_compile().
Fixes: #13208
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.
