Install pkg-config

sudo apt install pkg-config

This is VERY important, since we want this build of opencv-python to make use of the libraries we have already installed. Portability is no issue here. pkg-config generates .pc files that CMake will look into. Without this, CMake will not know where FFMPEG libraries are or if they are installed.

Compile opencv

1. get source

git clone --depth 1 --branch [version] https://github.com/opencv/opencv.git For example: 4.11.0 for version

Git Crash Course for Beginners

Preface
