The settings added by commit 3fe8e33f27 (Clang: Record Clang 16.0 flags
for our experimental C++ modules support, 2023-03-03, v3.26.0-rc6~6^2)
work only for the GNU-like `clang++` front-end, and not for the
MSVC-like `clang-cl` on Windows.
Also quote the path to `clang-scan-deps` to support spaces in its path.
Issue: #24611
Refactoring in commit 77982de955 (CMakePackageConfigHelpers: only emit
arch check if needed, 2023-01-29, v3.26.0-rc1~16^2) did not correctly
preserve the check for empty `CMAKE_SIZEOF_VOID_P`. Fix it.
The difference between the version files generated before and after is:
-if(CMAKE_SIZEOF_VOID_P STREQUAL "" OR "8" STREQUAL "")
+if("${CMAKE_SIZEOF_VOID_P}" STREQUAL "" OR "8" STREQUAL "")
This restores the check generated before the above-mentioned commit.

CMAKE_REQUIRED_FLAGS now notes that space-delimited string, not
;-list is required, which could be surprising compared to similar
options that do use ;-list
Revert commit 5b45a3d0ce (CheckCompilerFlag: Match the Clang "argument
unused" output for all languages, 2023-01-23, v3.26.0-rc1~38^2). It
broke existing projects that were silently tolerating unrelated unused
arguments in their checks for C and CXX. For example, using
`CFLAGS=-nostdinc` or `CXXFLAGS=-nostdinc++` causes those flags to be
used when driving the linker as well, and Clang warns they are unused in
that case.
Add a test case covering the now-restored behavior.
Fixes: #24591
GenerateExportHeader had a hidden state requirement that other
modules were included first. Considering include_guard, Modules
should include all they actually use.
FindCUDA's custom commands invoke `nvcc`, which invokes `cl`. Under VS
this is done without a `/FS` flag, so `.pdb` generation races if we
use `BuildInParallel`. The FindCUDA module has already been removed by
policy CMP0146 after being deprecated since CMake 3.10, so it is
simplest to just disallow this combination of features.
Issue: #24576
These extensions are used by convention for C++ module interface units
with Clang.
For now, do not add any tests using these extensions.
Very few compilers recognize them as C++ sources.
Tests can be added later as part of C++ modules support.
The `FindCUDA` module has been deprecated since CMake 3.10.
Add a policy to pretend it doesn't exist in order to encourage
projects to port away from it.
