> I'll be adding a `CUDA_ROOT` option to CMake that will be passed to clang as `--cuda-path`.

I'm not familiar with CMake and whether that option is picked up from an environment variable, but on Windows that environment variable that the CUDA installer sets is `CUDA_PATH`:

On Linux you are expected to add the <cuda root>/bin directory to the `PATH` environment variable.
