FetchContent_MakeAvailable() should be strongly preferred over
the direct use of FetchContent_Populate(). The latter was the only
method available before CMake 3.14, but the former is simpler and
offers more functionality. Restructure the docs and improve the
wording to steer the reader toward `FetchContent_MakeAvailable()`
as the preferred approach.
Also take the opportunity to pull out the variables that influence
behavior into their own section. They were easily missed when
buried in the docs for the FetchContent_Populate() command.
MPICH 3.4.2 now reports `-framework OpenCL` as one of its compilation
flag. The compile flag extraction is seeing it as a generic `-f` flag
and misses its argument. This ends up with a compile option of
`-framework` which eats the next flag (and may be very important).
It does not seem that passing `-framework` as a link flag is necessary
at this time, so that is being actively ignored for now.
Fixes: #22555
The macro's implementation converts a normal variable into a cache
variable intentionally, so both are set. Explicitly set CMP0126 to NEW
to avoid a warning in trace mode. This won't affect the module behavior
because the code path does not activate if a normal variable is already
defined anyway.
Fixes: #22548
Our `find_program` calls specify `HINTS` to look in the toolchain's
directory first, and then in `PATH`. `CMAKE_PREFIX_PATH` may be
specified by the user to help find packages for project dependencies,
but this should not override the binutils.
Fixes: #22512
The `TEST_FILTER` argument can be used to filter tests during the
discovery phase. It combines `--gtest_filter=<expr>` with the
`--gtest_list_tests` argument when invoking the test excutable for
listing defined tests.

Since commit 4aed96e230 (Apple: Set CMAKE_SHARED_LIBRARY_RUNTIME_C_FLAG
on non-macOS too, 2021-04-06, v3.20.1~5^2) we always enable support for
linking with `-rpath`. The intention of the change was to enable using
the flag on iOS, tvOS and watchOS by avoiding a Darwin-specific version
check. However, removing the check broke support for OS X 10.4 because
the flag is not supported on that version.
Restore a form of the check that disables the flag on OS X < 10.5 while
still allowing it for the other Apple platforms. Since no one is doing
iOS/tvOS/etc development on 10.4, this change should have no unintended
side effects.
Fixes: #22490
Fix a cut-n-paste error from commit fd4406f33e (IRSL: Add Intel compiler
support, 2017-08-16, v3.10.0-rc1~187^2). Make the checked and used
paths match.
The behavior was added by commit 7ebc1cb2ff (Haiku: Several fixes to
platform module, 2013-10-05, v3.0.0-rc1~541^2~3), but was not explained
in its commit message. No other platform modules do this.
The include-once behavior results in incorrect variables set in some
larger projects, e.g. .NET Core, particularly when cross-compiling,
`CMAKE_DL_LIBS` being one of these. Remove it.
