[Buildroot] [PATCH v7 13/33] package/efl/libefl: add OpenGL/OpenGLES support

Romain Naour romain.naour at openwide.fr
Mon Dec 7 21:29:15 UTC 2015


Allow to enable graphic acceleration using OpenGL or
OpenGLES with efl libraries.

The full opengl option depend on X11, because full openGL means GLX,
which means X11.
