Using VS- build in Clang
Are triplets for manually installed LLVM ? Can it be used with build-in Clang support in VS 2022 ?
I tried x64-win-llvm and getting the following:
Unable to find a valid Visual Studio instance with toolset version ClangCL The following Visual Studio instances were considered: C:\Program Files\Microsoft Visual Studio\2022\Enterprise The following paths were examined for Visual Studio instances: C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Auxiliary/Build\vcvarsall.bat C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools/MSVC\14.36.32532\bin/HostX86/x86\dumpbin.exe
CLang-CL toolchain is in C:\Program Files\Microsoft Visual Studio\2022\Enterprise\VC\Tools\Llvm
You need to have:
installed which is not the same as
In general it should work with either.
Yes, I have them both.
Any other CMake project works with -TClangCL properly in the same setup.

Unable to find a valid Visual Studio instance
with toolset version ClangCL
means that vcpkg tried to locate a toolset with the name ClangCL. However, vcpkg doesn't know how to look up custom toolsets apart from the vc14x ones.
https://github.com/Neumann-A/my-vcpkg-triplets/blob/cb4dc2eb68339a39e9f0de11fa530655c6f09aed/x64-win-llvm.cmake#L10-L12
The if(DEFINED VCPKG_PLATFORM_TOOLSET) is a trick to make vcpkg lookup vcvars without having a PLATFORM_TOOLSET defined and thus not looking for the ClangCL toolset but a normal vc14x one and then after the lookup switches the toolset back to ClangCL via the logic in the truplet.
Have you setup some environment variable which modifies the lookup behavior or have you modified the triplet?
