Building (mostly copied from libigl-python-bindings)

Testing cibuildwheel locally

Install whichever version of Python from the official website and then run:

/Library/Frameworks/Python.framework/Versions/3.12/bin/python3.12 -m venv venv-official-3.12
source venv-official-3.12/bin/activate
python -m pip install cibuildwheel
CIBW_BUILD="cp312-*" python -m cibuildwheel --output-dir wheels --platform macos

Downloading all the artifacts

A successful .github/workflows/wheels.yml run will generate a lot of .whl files. To download these all at once, you can use the following command:

mkdir -p wheels
cd wheels
gh run download [runid]

Uploading to TestPyPI / PyPI

Then these can be uploaded to pypi using:

python -m twine upload --repository testpypi wheels/*/*.whl wheels/*/*.tar.gz
