    - name: Determine stack root
      ## 2023-11-21 https://github.com/commercialhaskell/stack/issues/6340
      ## Asking stack for the stack root unfortunately does not work
      ## if stack is not fully operational (meaning e.g. that GHC is installed)
      ## so we hardcode its location instead.

        STACK_ROOT="C:/Users/runneradmin/AppData/Local/Programs/stack/x86_64-windows"
        echo STACK_ROOT="${STACK_ROOT}" >> "${GITHUB_ENV}"

      #   STACK_ROOT="$(stack --system-ghc --no-install-ghc path --stack-root || echo "C:/Users/runneradmin/AppData/Local/Programs/stack/x86_64-windows")"
      #   echo "STACK_ROOT = ${STACK_ROOT}"
      #   echo STACK_ROOT="${STACK_ROOT}" >> "${GITHUB_ENV}"
      # What about C:/Users/runneradmin/AppData/Roaming/stack ?
