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.

Rà soát cấu hình đóng gói cho các dự án cuda-bindings, cuda-core và cuda-python, sau đó so sánh với các archive release của toàn bộ repository. Xác minh rằng mỗi dự án có thể tạo một source distribution riêng có thể sử dụng bởi một bản build PEP 517 tiêu chuẩn, đồng thời vẫn giữ nguyên các dependency giữa các package; công việc được xem là hoàn tất khi các distribution có thể được đính kèm vào các release hoặc phát hành lên PyPI.
