Except for gst/gl/gstglfuncs.h It is up to the client app to include these headers. It is coherent with the fact that gstreamer-gl.pc does not require any egl.pc/gles.pc. I.e. it is the responsability of the app to search these headers within its build setup. For example gstreamer-vaapi includes explicitly EGL/egl.h and search for it in its configure.ac. For example with this patch, if an app includes the headers gst/gl/egl/gstglcontext_egl.h gst/gl/egl/gstgldisplay_egl.h gst/gl/egl/gstglmemoryegl.h it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h. Which is good because the app might want to use the gstgl api only without the need to bother about gl headers. Also added a test: cd tests/check && make libs/gstglheaders.check https://bugzilla.gnome.org/show_bug.cgi?id=784779
