 Hi devteam,

 in order to build libmythui , i have to add the following
 CXXFFLAGS

 -DGL_GLEXT_PROTOTYPES

 otherwise the build will fail with undefined references to

Comment:

 Mark, I'm sending this your way since you're the man with the plan for
 OpenGL ES.

 Not sure if this is something that needs fixing in configure or in the
 .pro files, but "MythTV - configure script" is a better fit than
 "Contributed Scripts & Apps".
