CMake expects that if this is set then it is an absolute path with forward slashes.  Either the infrastructure here will need to learn how to give `%(workdir)` forward slashes, or the change to CMake I mentioned previously will need to be made.

Alternatively, put the path to `clang-cl` in the `PATH` and set `CMAKE_C_COMPILER=clang-cl`.
