I think pkg-config is the right tool. Its good to be dependent on
these tools so as to locate the libraries.

For example, in some systems the glfw.h file ( OpenGL related file )
is in /usr/include/GL/glfw.h and some have it in /usr/include/GLFW.h.
Mac has it in /usr/x11/include/GL/glfw.h I guess. So pkg-config takes
care of finding the files and libraries hence avoiding manual efforts.
