Build from source python 3.12 fails about opencv-python

[sibocw]

Thank you @zhanwenchen, I also encountered the same issue (even after following the StackOverflow answer above), and solved it the same way. I think the ==59.2.0 prevents pip from using the most up-to-date setuptools that has this API change addressed.

Is there a particular reason why there's such a strict requirement for setuptools? Can I make a PR to remove it (or change it to >=59.2.0)?

I encountered the same problem while running pip wheel . --verbose |& tee install_opencv.log. It worked after removing the ==59.2.0" from the "setuptools==59.2.0" https://github.com/opencv/opencv-python/blob/4.x/pyproject.toml#L16.

I already tried that and it didn't work.

I'm also getting the same error with the latest merged updates:
