I'm having the same error as above. Note I'm running on Apple Silicon. I did set USE_LLVM_BREW=true after brew installing llvm and cmake. Any guidance would be appreciated!

FAISS needs OpenMP to compile: https://github.com/facebookresearch/faiss/blob/main/INSTALL.md. Can you possibly try brew install libomp?
