调研方向

该 issue 没有列出任何仓库文件或测试。首先检查已安装 wheel 中 Linux .so 文件的内容,并将提议的 cv2.distutils 接口与 NumPy 的 include 和 library 查找进行比较;完整的解决方案需要一个达成共识的范围,以及为链接到该 wheel 的使用者提供可复现的支持,其中包括 Windows 问题。

描述

enhancement

First off, thanks for this project, it saves a ton of time and I'm really happy that it exists. It makes it a lot easier to get OpenCV installed for the high school students I work with.

I'd like to take a C++ library that uses OpenCV, wrap it with cython, and link it to the OpenCV bits in the binary provided by the installed wheel. This would allow users to just install the wheel of the other library + the opencv-python wheel, as opposed to having to compile their own version.

Has anyone tried this yet? A cursory look at the linux .so files indicate that it exports all of the normal OpenCV symbols, so in theory if you just include the right headers and link to it then it should just work (though maybe not for Windows)... I think that one would add an additional cv2 module (cv2.distutils?) that could provide a list of includes/libraries, similar to how numpy works.

If there's no opposition to this, I might try this out in a week or three to see how it goes.
