You may want to build macOS arm64 wheel on arm64 CI runner so you can run test for both x86_64 and arm64 part of the wheel:

pywebp/.github/workflows/build_and_test.yml

# TODO: Use arm64 CI runner when available

I am trying to build pywebp with macos-14. During cibuildwheel test for the built universal2 wheel, it errored out as venv for testing x86_64 is reused for testing arm64, which contained x86_64 version of Pillow and cause error: https://github.com/laggykiller/pywebp/actions/runs/8074750021/job/22060570579#step:5:2147 . This is also discussed in pypa/cibuildwheel#1746 (comment) and fixed in pypa/cibuildwheel#1750 .

I can confirm that pywebp builds without error with master branch of cibuildwheel which contain that fix (https://github.com/laggykiller/pywebp/actions/runs/8074902563/job/22060951096), however cibuildwheel has not released a new version that contain that fix. I will submit a PR once cibuildwheel release a new version.

btw Beside allowing tests, seems like using macos-14 shaves 1 minute of build time

btw From working on my personal project that also use conan, conan profile is not regenerated if it already exist and -f flag not present. Though it probably won't affect this project (This project does not use the cmake profile generated by conan), rebuilding without updated conan profile may cause much headache (See tttapa/py-build-cmake#24). While we are at it, I will also add -f flag to conan profile detect in the PR.

That all sounds good, thank you!
