How to specify CUDA path?

[LHY-HongyangLi]

Hi @FindDefinition , I am compiling spconv from source and I notice that PCCM seems hardcode the path of cuda as "/usr/local/cuda/lib64". However, as a non-root user, I can not install cuda at this path. So I wonder how to specify a custom CUDA path?

You can modify cuda path in cumm/common.py get_cuda_include_lib if you want to build from source.
