How let pip recognize some packages installed by cmake?

Question

I have installed some packages build from source using cmake, for example, opencv, it was built with many customized options , enabled cuda, openvino, etc.

but it can't be recognized by pip.

pip3 show opencv
WARNING: Package(s) not found: opencv

pip3 show python_opencv
WARNING: Package(s) not found: python_opencv

pip3 show python-opencv
WARNING: Package(s) not found: python-opencv

pip3 show opencv-python
WARNING: Package(s) not found: opencv-python

python3 -c "import cv2;print( cv2.__version__)"
4.5.5-openvino

So when I try to install some other packages like gym that depend on python-opencv, it will try to install python-opencv, and a lot of other dependent packages, like cmake.

how to let pip known that I have an opencv package installed. or how to hack pip to let it think this dependency is satisfied?
