cibuildwheel (which is an official, supported tool) has made this enormously easier. I test and generate wheels with a compiled (Rust! Because of course) extension using a Cython bridge for all supported Python versions for 32-bit and 64-bit Windows, macOS x86_64 and arm64, and whatever manylinux is calling itself this week. No user compilation required. It took about half a day to set up, and is extremely well documented.
