# The classes inheritance and build process here is a bit tricky.
# PyTango uses python build (PEP517) which runs the build using
# scikit-build-core which in turn uses CMake to build the extension.
# So first we inherit cmake to generate cmake configuration (toolchain.cmake)
# and then we also inherit python_pep517 to overwrite
# do_configure/do_compile/do_install with the correct ones.
# This almost works, but you have to play a bit with CMAKE_ARGS.

# TODO: Why is python include dir not found automatically?
