Build Error -> pip install submodules

[lzhangsh]

Has anyone encountered this issue before?
When setting up the environment, I keep getting the error: UserWarning: Error checking compiler version for cl: Command 'cl' returned non-zero exit status 2. warnings.warn(f'Error checking compiler version for {compiler}: {error}'). Even after adding Visual Studio's cl.exe to the system Path environment variables, the error persists, making it impossible to compile simple-knn and diff-rasterization.

I’ve tried all the suggestions from Stack Overflow and GitHub, including downgrading or upgrading CUDA versions, Python, and PyTorch, but nothing works. Switching from Visual Studio 2022 to 2019 didn’t help either.
