--enable-shared-glapi creates another library (libglapi.so). This library
contains de shared code between OpenGL (let'S say desktop), OpenGL ES and maybe
even OpenVG, instead of having duplicated code in each GL implementation.

However, in my case, it doesn't have to do with a library left somewhere. As I
tested and showed, everything is pointing to the right ones.
