Is it correct to assume that for every opencv header included into the cpp file

#include <opencv2/xxx.hpp>

-lopencv_xxx needs to be added to g++ command line?

Add this `pkg-config --libs --cflags opencv` (OpenCV 2.x and 3.x) or `pkg-config --libs --cflags opencv4` -std=c++11 (OpenCV 4.x) to your compilation line and you will have everything you need to compile.
