so the header file actually needs packages for it to work, I don't know how to install it that is why I am posting the error here.
-lGL -lpthread -lpng -lstdc++fs -std=c++17
/usr/bin/ld: cannot find -lGL
/usr/bin/ld: cannot find -lpng
collect2: error: ld returned 1 exit status
these is the error statement found when I try to compile, please tell me how to install these libraries, BTW I am using Ubuntu 20.04.
