General cuda-python

Is your feature request related to a problem? Please describe.

Currently, the cuda-bindings, cuda-core and cuda-python packages on PyPI publish only binary wheels. Source code is available from archives attached to releases, but it includes the whole repository and therefore does not integrate well with standard PEP 517 build process (read: you can't just pip install cuda-python-v12.9.0.tar.gz).

Describe the solution you'd like

While we can work around it, as downstream packagers we would find it much cleaner if you could provide source distributions for each project separately. If you don't want to upload them to PyPI, attaching to releases would also work.

Describe alternatives you've considered

No response

Additional context

I understand that there are currently some cross-package dependencies that require using the monorepo archive. However, I think they could be solved cleanly with help of some symlinks that turn into included subdirectories in sdist. If you agree, I can experiment a bit and prepare a pull request if I get something neat working.

Hi Michal, thanks for reaching out. Uploading sdists to PyPI, as you might have heard, has some issues that could trap users. Therefore,

If you don't want to upload them to PyPI, attaching to releases would also work.

this seems like a good idea. We do plan to attach more release artifacts to GitHub Releases (#742).

Thanks for getting back to me. I've created #758 to fix the inability to build wheel from cuda-python sdist right now.
