Print an error message for invalid values of
`CTEST_CUSTOM_TEST_OUTPUT_TRUNCATION` in a ctest dashboard script.
The option was added by commit 140704d443 (ctest: add option for
output truncation, 2022-03-07, v3.24.0-rc1~513^2).
Fixes: #23869
We've made several attempts to add a dummy symbol to `mocs_compilation.cpp`
when there are no automoc sources:
* commit 4a9daae483 (automoc: silence linker warning on macos,
2022-05-25, v3.24.0-rc1~55^2)
* commit 844244ccdc (automoc: avoid compiler warnings in linker-warning-
silencing code, 2022-08-10, v3.24.1~6^2)
* commit fc8628389f (automoc: avoid more compiler warnings in linker-
warning-silencing code, 2022-08-29)
The last attempt derives a symbol name from the path to the source
file, but that breaks reproducible builds because it is not stable
w.r.t. the location of the build tree. Revert all these attempts
for the 3.24 release series, and return to what 3.23 and below did.
Further investigation will be needed to resolve the original issue.

f972e4fd3a cmVSGenerator: Add support for two-part toolset versions for Visual Studio
Acked-by: Kitware Robot <kwrobot@kitware.com>
Merge-request: !7637
Introduce a new signature for try_compile (and try_run) which removes
the `bindir` argument and requires the SOURCES tag. This will eventually
allow us to add other ways of providing sources, but also allows us to
change the behavior without breaking compatibility.
The old signature uses a special, but non-unique temporary location
inside the specified `bindir`, which conventionally is just the
project's build directory. The new signature unconditionally uses the a
unique temporary directory which is unconditionally within the project's
build directory (which is no longer separately specified). This ensures
that successive runs do not overwrite previous runs, will simplify
debugging, and should also, eventually, allow us to execute multiple
trials in parallel.
Add a cross-platform wrapper over mkdtemp. This will allow us to create
guaranteed-unique directories. On POSIX platforms, this is simply a
wrapper over mkdtemp. On Windows, we take a brute-force approach using
C++11's random facilities and relying on attempts to create an existing
directory resulting in an error. (This approach is very possibly how
mkdtemp is implemented internally, and should be suitable for any
platform if needed, although at present it only uses a partial set of
substitution characters since Windows likely implies a case-insensitive
file system.)
Enables the Global Visual Studio Versioned Generator to use two-part toolset versions,
if only one toolset has that version number. For example, (14.32 is specified when
14.32.32142 and 14.32.23242 are installed). This change also add a unique return code
and message if a two-part version is used when multiple matching versions are present.
Fixes: #23933
