Scikit-build 0.12.0

The scikit-build GitHub organization welcomes @henryiii and @mayeut as core contributors and maintainers. Both are also maintainers of cibuildwheel.

@henryiii is a pybind11 and pypa/build maintainer, has been instrumental in adding Apple Silicon support, adding support for Visual Studio 2019, updating the Continuous Integration infrastructure, as well as helping review & integrate contributions, and addressing miscellaneous issues. Additionally, @henryiii has worked on an example project to build with pybind11 and scikit-build.

@mayeut is a manylinux maintainer and focused his effort on updating the cmake-python-distributions and ninja-python-distributions so that the corresponding wheels are available on all supported platforms including Apple Silicon and all flavors of manylinux.
