Modern equivalent of --with-egl-window-system=rpi ?

[Julien Isorce]

Try to uninstall all mesa packages. You should not have the directory
/usr/include/GL/ .

Instead just install libraspberrypi-dev (which contains
/opt/vc/include/GLES2)

(Passing --disable-opengl should prevent from using /usr/include/GL path )

Cheers
Julien
