Rasterio wheel builds based on https://github.com/multi-build/multibuild.
This project builds the rasterio binary distributions that are uploaded to PyPI. Those distributions, or "wheels", include a GDAL shared library and other shared libraries supporting many, but not all, of GDAL's format drivers. If you need the rarely used formats and compressors not found in these wheels, you may find them in the conda-forge conda channel, or in Docker images published by the GDAL project.
Wheels for x86_64 manylinux2014 and macos Pythons 3.7-3.10 are built by GitHub Actions.
Wheels for aarch64 linux and arm64 macos are complicated by limited availability of build instances and cross-compilation issues within GDAL's dependencies. See the issue tracker for details.
Wheels for windows are not available. We don't have enough Windows experience in this project yet.
