[Python] Failed to build installable wheels for some pyproject.toml based projects...

I was tried to install llama-cpp-python via pip, but have error with installation

command that I wrote CMAKE_ARGS="-DLLAMA_METAL_EMBED_LIBRARY=ON -DLLAMA_METAL=on" pip install llama-cpp-python --no-cache-dir

so, what I have

python 3.12.10 pip 25.2 macOS 15.6 (24G84) MacBook Air m2

what I did to resolve this issue:

1. installed Xcode from App Store
2. installed Xcode command tools via this command xcode-select —install
3. replaced command tools path to path with Xcode application (sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer)
4. installed cmake and libomp via brew
5. changed path: CMAKE_ARGS="-DLLAMA_METAL=on"
6. tried to install llama-cpp-python via this command: pip install llama-cpp-python --force-reinstall --no-cache-dir

p.s.: I have installed conda
