Additional Context

I am trying to build the package on M1 laptop but keep getting this error. The OpenCV was installed under the /opt/homebrew/opt/opencv@3.

Thank you for reporting the issue.
This is fixed by #592.
You can also work around this issue by linking OpenCV statically (python build.py build --desktop cpu --opencv cmake -vv).

Thanks for the swift fix! It works now.
