The `FindPythonInterp` and `FindPythonLibs` modules have been deprecated
since CMake 3.12. Add a policy to pretend they do not exist in order to
encourage projects to port to `FindPython` or `FindPython{2,3}`.
Since commit cf82300a63 (BinUtils: Clarify search logic and make it more
consistent, 2021-05-27, v3.21.0-rc1~119^2~2) we prefer `llvm-strip` over
`strip` when using Clang. However, `llvm-strip` seems to produce
unusable binaries in cases involving chained fixups. Prefer Apple's
`strip` over `llvm-strip` on `APPLE` platforms.
We still need to consider `llvm-strip` as a fallback as explained for
`llvm-ar` by commit fee36b7a78 (BinUtils: Restore llvm-ar fallback on
Apple platforms, 2022-03-15, v3.23.0-rc4~12^2).
Issue: #24601
Some HDF5 compiler wrappers do not support source file paths that
contain spaces. Pass source files to them using a file name in the
current working directory to avoid spaces.
The `-wmo` flag added by commit 6063428de7 (Swift: Update default build
flags, 2022-10-03, v3.26.0-rc1~585^2~1) behaves differently with the old
driver. Detect when the old driver is being used, and avoid adding that
flag.
Fixes: #24641
Since commit 14c46fb16a (FindHDF5: Find C component with only CXX
compiler, 2022-12-13, v3.26.0-rc1~175^2), if CXX is enabled but C is
not, the `_HDF5_test_regular_compiler_C` helper writes a `.cpp` source
but the `_HDF5_invoke_compiler` still expects a `.c` source. Refactor
the logic to select a name for the source file up front, and use it in
both helpers.

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
