C++ module sources should not be included by any other TUs, so their
presence cannot matter for order-only dependencies of the entire target.
Exclude them.
Update CMP0154 to take this into consideration and add tests to the
`CXXModules` suite (which already deals with module support detection).
Prior to 5420639a, execute_process() would open INPUT_FILE, OUTPUT_FILE,
and ERROR_FILE relative to the WORKING_DIRECTORY argument if it was
provided. Restore this behavior for backwards compatibility.
Fixes: #25338
Changing the `timestamp` file to `timestamp_$<CONFIG>` causes some user
projects to break when using Qt versions older than 6.6.
Revert commit fddd0f0443 (Autogen: AUTO*_EXECUTABLE: add support for
per-config values, 2023-06-14, v3.28.0-rc1~96^2~1) pending further
investigation.
Issue: #20074
Revert commit e454314daa (NinjaMultiConfig: Update tests for the new
dependency change, 2023-07-05, v3.28.0-rc1~96^2) because we are about
to revert the change for which it updated tests.
Under CMP0155's NEW behavior, projects that explicitly enable C++20
support with `set(CMAKE_CXX_STANDARD 20)` may also explicitly
disable scanning with `set(CMAKE_CXX_SCAN_FOR_MODULES OFF)`.
We already propagate `CMAKE_CXX_STANDARD` into `try_compile` test
projects, so propagate `CMAKE_CXX_SCAN_FOR_MODULES` too.

The compiler does not yet support everything needed to integrate well
with the MSVC ABI, in particular for runtime library selection and debug
format selection. Document them in FIXME comments and leave this
support undocumented by CMake for now.

These are printed by LLVM-based compiler drivers targeting the MSVC ABI.
In our use case for this, `CMAKE_LINKER` may not yet be known, so do
not include it in the test data.

Now that scanning support is no longer experimental, the logic for
whether or not to scan C++ 20 sources is now important because all
projects are now exposted to the logic. Make the scanning rules explicit
in the documentation and rework the queries to localize all of the
associated logic.
A policy to handle the ultimate fallback logic will be implemented in a
following commit.
This provides a utility macro which prints out:
- location of the call;
- the expression being evaluated; and
- the value of the expression.
Evaluates to the value of the expression.
Inspired by Rust's `dbg!` macro.

Since refactoring in commit 0a5aeaf302 (cmCTestRunTest: Consolidate test
timeout selection logic, 2023-05-04, v3.27.0-rc1~120^2) we accidentally
truncate `--timeout` values to ctest's default `TimeOut`. Fix the
logic to prefer the flag whenever the `TIMEOUT` property is not set.
In combination with the prior refactoring, this also fixes a bug that
caused `--timeout` values of 10000000 seconds or more to be ignored.

Since commit fddd0f0443 (Autogen: AUTO*_EXECUTABLE: add support for
per-config values, 2023-06-14) we do not correctly generate outputs
for one configuration after another configuration has been built.
Fix this:
- Revert some config based stuff for `Xcode` due to the `$<CONFIG>`
genex usage limitation in source files with `Xcode`.
- For multi-config generators use a per-config `timestamp_$<CONFIG>`
file instead of one `timestamp` file.

which ignores our `-Xlinker -adhoc_codesign` flag, prioritizes its own
`-Xlinker -no_adhoc_codesign` flag, and does not add an ad-hoc signature
at link time.
