llvm 17 now defaults to openmp 5.1; see LLVM commit `0c6f2f629cc0`.
It makes FindOpenMP set OPENMP_FOUND and OpenMP_C_SPEC_DATE, but not
OpenMP_C_VERSION, because it doesn't know the version mapping.
Add the spec date to the version mapping for 5.1 and 5.2 to make
things work again.
Refactoring in commit deff0e638d (CUDA: Factor out helper to parse NVCC
implicit compiler and linker flags, 2023-09-15, v3.28.0-rc1~63^2~6)
incorrectly dropped detection of the default CUDA architecture and
the CUDA toolkit include directories from the code path used for
Visual Studio generators. However, CMakeNVCCParseImplicitInfo is
now general enough that we no longer need a VS-specific code path.
Fixes: #25378
Revert commit cf2ad9995a (GetPrerequisites: Ignore relative paths
printed by ldd, 2023-02-20, v3.27.0-rc1~459^2) because it regressed
existing use cases. We will need to find another solution to the use
case motivating the change.
Fixes: #25372
This was accidentally broken by commit 31adc11030 (FindProtobuf: Add
PLUGIN_OPTIONS and PROTOC_OPTIONS to protobuf_generate, 2023-06-29,
v3.28.0-rc1~409^2~2).
Fixes: #25368
-fno-ansi-escape-codes is used only on Windows by Clang.
Without the flag color diagnostics are displayed only if clang.exe
is executed directly. Build tools like ninja and mingw32-make
will not display colored diagnostics.
Using -fno-ansi-escape-codes will make the build tools pass
the colored diagnostics to the calling application e.g IDE.

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.

Improves the handling of CUDA layouts where we have multiple include
and library directories listed in the output of `nvcc -v`. This
updates both when the CUDA language is enabled or not.

Update the Clang version checks added by
* commit eacacc70fc (Clang: use -std=c++23 for Clang 17.0+,
2023-05-08, v3.27.0-rc1~115^2)
* commit 0183956d30 (Clang: C++26 support,
2023-05-16, v3.27.0-rc1~85^2)
to account for Android NDK r26's distribution of a Clang based on a
development version of LLVM/Clang 17.0 that pre-dated addition of
these flags.
Follow the pattern from commit 12e6796b62 (Android: Do not pass
non-existent Clang -std flags, 2018-04-02, v3.12.0-rc1~284^2),
which fixed the same problem for `-std=c++17`.

ROCm may not install the `hip-lang` cmake package on NVIDIA platforms.
Skip verifying its presence. We do not use it for NVIDIA platforms anyway.
