There are plenty of questions and answers relating to this, but none of them have gotten me past my current problem. I can build using CMake/Ninja/clang-cl fine from within Visual Studio, but I want this to be done within a Github Action so I need to be able to do it from the command line - but it fails the configuration stage.

Running from Powershell:

& 'C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat' x64 10.0.22000.0
cmake -G "Ninja" `
    -DVCPKG_TARGET_TRIPLET:STRING="x64-windows-static" `
    -DCMAKE_CXX_COMPILER:FILEPATH="C:/PROGRAM FILES/MICROSOFT VISUAL STUDIO/2022/COMMUNITY/VC/Tools/Llvm/x64/bin/clang-cl.exe" `
    -DCMAKE_C_COMPILER:FILEPATH="C:/PROGRAM FILES/MICROSOFT VISUAL STUDIO/2022/COMMUNITY/VC/Tools/Llvm/x64/bin/clang-cl.exe" `
    -DCMAKE_RC_COMPILER:FILEPATH="C:/PROGRAM FILES/MICROSOFT VISUAL STUDIO/2022/COMMUNITY/VC/Tools/Llvm/x64/bin/llvm-rc.exe" `
    -DCMAKE_MAKE_PROGRAM="C:\PROGRAM FILES\MICROSOFT VISUAL STUDIO\2022\COMMUNITY\COMMON7\IDE\COMMONEXTENSIONS\MICROSOFT\CMAKE\Ninja\ninja.exe" `
    ..\arg_router\

Yields:

Those libraries are installed in C:\Program Files (x86)\Windows Kits\10\Lib\10.0.22000.0\um\x64 which I would have thought vcvarsall.bat would have setup some env var that points to them - but clearly it didn't. What's weirder is that when I configure CMake from within VS, it doesn't need to pass the CMAKE_RC_COMPILER arg but if I don't then it fails stating that rc.exe can't be found.

Clearly VS is doing some extra configuration in the background before CMake is configured - what is it!?

As an extra data point, if I try to run the above CMake configuration command within the 'Developer Powershell for VS 2022', it fails for a different reason:

  • AFAIK clang is only in visual studio for static analysis not for actual compiling/building stuff and you try to force cmake to do that with your variables – Superlokkus Feb 18 '22 at 14:27

    Nope, when I build from VS it is using clang-cl, here's a line from the output from the config stage: `[CMake] -- The CXX compiler identification is Clang 13.0.0 with MSVC-like command-line` – cmannett85 Feb 18 '22 at 14:39
  • Then I have no clue except what you probably already know: Windows is a terrible development platform, and diverting from the MSVC Compiler brings you even more into hell. My sympathy. – Superlokkus Feb 18 '22 at 14:44

    I've created a VS issue for this: https://developercommunity.visualstudio.com/t/Unable-to-build-using-clang-cl-CMake-a/1670695 – cmannett85 Feb 24 '22 at 16:02
  • Is this resolved? I'm still facing the issue. – harry Jun 19 '23 at 04:04
