Hi @edoardob90 - looking at the wheel build failures in Github Actions, I think the issue may be related to how CLEED is compiled via the custom Extension class used with setuptools.setup within setup.py and integrated via PEP517 pyproject.toml build hook. Looking into compiling native code recently myself I found a solution that may work well with your existing CMake files via scikit-build which should do most of the native extension heavy lifting for you 🤞

Thank you @Liam-Deacon for the comment.

I indeed had a look into scikit-build but couldn't figure out properly how to adapt the examples based on C++ to our interface with a pure C code. The current setup is a bit "dirty" but it works.

Other hints on to use that build system are obviously welcomed.

Glad to see you got it building - nice work!
