actions/checkout path to WSL

[scivision]

I want to run a CMake project in WSL, but have trouble programmatically finding the top-level project source directory. I didn't quite get how to do this from the existing setup-wsl Discussions.

Here is a failed run: https://github.com/scivision/detect-windows-subsystem-for-linux/actions/runs/7023130945/job/19108936615

The log:

Run cmake -S $(wslpath -u ${GITHUB_WORKSPACE}) -Bbuild
  cmake -S $(wslpath -u ${GITHUB_WORKSPACE}) -Bbuild
  shell: D:\a\_temp\wsl-shell-wrapper\wsl-bash.BAT {0}
  env:
    CTEST_NO_TESTS_ACTION: error
    WSLENV: GITHUB_WORKSPACE
CMake Error: The source directory "/mnt/d/a/detect-windows-subsystem-for-linux/detect-windows-subsystem-for-linux" does not appear to contain CMakeLists.txt.

The yaml:

 wsl:
    runs-on: windows-latest

    env:
      WSLENV: GITHUB_WORKSPACE

    defaults:
      run:
          shell: wsl-bash {0}

    steps:
    - uses: Vampire/setup-wsl@v2
      with:
        additional-packages:
          cmake make gcc g++

    - run: cmake -S $(wslpath -u ${GITHUB_WORKSPACE}) -Bbuild
    - run: cmake --build build
    - run: ctest --test-dir build -V

You simply forgot to make the checkout in the wsl job. :-)
The wslpath magic should also not really be necessary, I think your working directory should stay the same.
But I assume it was just a try to overcome the problem.

[scivision]

correct, the wslpath was unneeded
