Issue: Your installed Caffe2 version uses protobuf but the protobuf library cannot be found.

[zhoufy20]

Dear developers of deepmd-gnn:
I get some trouble when execute export CMAKE_PREFIX_PATH=$(python -c "import torch;print(torch.utils.cmake_prefix_path)") and pip install . Below are callback error:

        be found.  Did you accidentally remove it, or have you set the right
        CMAKE_PREFIX_PATH? If you do not have protobuf, you will need to install
        protobuf and set the library path accordingly.

Thank you for your assistance!

        Your installed Caffe2 version uses protobuf but the protobuf library cannot
        be found.  Did you accidentally remove it, or have you set the right
        CMAKE_PREFIX_PATH?

According to the error message, appending the prefix of protobuf (it should be in CONDA_PREFIX) to CMAKE_PREFIX_PATH may resolve the problem.

Indeed, I cannot reproduce the error.
