CMake Wheels

Wheel build backend using CMake, to package anything with pip and distribute on PyPI.

Following those relevant PEPs:

PEP 427, The Wheel Binary Package Format 1.0
PEP 517, A build-system independent format for source trees
PEP 518, Specifying Minimum Build System Requirements for Python Projects
PEP 600, Future ‘manylinux’ Platform Tags for Portable Linux Built Distributions
PEP 621, Storing project metadata in pyproject.toml

Basic idea

Glue between PEP 517 build_wheel function and modern CMake standard project configuration / build / test / install
Install in ${PYTHON_SITELIB}/cmeel.prefix/
- As there is a dot, it is not a valid python module name, so no risk of importing anything there by mistake
- Play well with others, as everything is confined to ${PYTHON_SITELIB}/cmeel.prefix
- ${PYTHON_SITELIB}/cmeel.pth automatically load ${PYTHON_SITELIB}/cmeel.prefix/${PYTHON_SITELIB}, so python packages work out of the box
- Existing ${PYTHON_SITELIB}/cmeel.prefix are automatically added to $CMAKE_PREFIX_PATH, so we can build CMake packages whose dependencies are provided by other CMake packages installed with cmeel
- Stuff in ${PYTHON_SITELIB}/cmeel.prefix/bin is exposed via cmeel.run:cmeel_run
