Compiling cpp using
g++ -std=c++11 decolor.cpp -o fish -I /home/a/Downloads/installation/OpenCV-3.4/include -L /home/a/Downloads/installation/OpenCV-3.4/lib -lopencv_core -lopencv_highgui
fails saying
/usr/bin/ld: cannot find -lopencv_highgui
The command above I copied elsewhere without proper understanding the -lopencv_highgui bit. What is it for?
-lopencv_highgui is an openCV module. Should it be present as a directory?
command find / -name opencv_highgui
finds nothing
However there is libopencv_highgui in lib directory
Shall I drop -lopencv_highgui from the command or I still need to install opencv_highgu module
