[Help needed] Compile opencv with python binding with vcpkg

[talregev]

I vcpkg install python3 then vcpkg install opencv4
It didn't bind opencv4 with python automatically. then I bind it manually from buildtree
then import cv2

I get an error.
Can some help me to compile opencv4 with python binding with vcpkg? thank you.
