cmake checks for the presence of cairo-gl and cairo-egl during the configure stage, but the code assumes it present regardless of what cmake found. 

cmake:
-- checking for module 'cairo-gl'
--   found cairo-gl, version 1.14.0
-- checking for module 'cairo-egl'
--   package 'cairo-egl' not found
-- Found CairoGL: /usr/local/include/cairo;/usr/local/include/glib-2.0;/usr/local/lib/glib-2.0/include;/usr/local/include/pixman-1;/usr/local/include/freetype2;/usr/local/include/libpng16;/usr/local/include/libdrm;/usr/local/include;CAIRO_EGL_INCLUDE_DIRS (Required is at least version "1.10.2")
