Since EGL is not usually used on desktop GL. I am not sure weather it is working on AMD devices, or on Windows.

So I add a macro to make EGL optional.

My CentOS 7 server doesn't have a GPU, I got an error when running ffmpeg with gltransition filter:

libEGL warning: DRI2: xcb_connect failed
libEGL warning: DRI2: xcb_connect failed
Segmentation fault
