When no X11 headers are present eglplatform.h will break unless certain defines are set prior to its inclusion. including wayland-egl.h defines WL_EGL_PLATFORM which will stop the attempted inclusion of the X11 headers. Maybe this isn't the best solution to the problem, but it's harmless and gets the job done.
