-modules will be used to link AOT generated binaries. These modules can be
-overridden by setting the following variables:

-|-------------------------|----------------------------------|
-| `OPENGL_egl_LIBRARY`    | Path to the EGL library.         |

-The OpenGL paths will need to be set if you intend to use OpenGL with X11 on
