# - Try to detect some SDL gles support
|
|
# Once done this will define
|
|
#
|
|
# SDLGLES_FOUND - system has gles support in SDL
|
|
# SDLGLES_TYPE - Native or EGL
|
|
# SDLGLES_INCLUDE_DIR - include directory for SDL gles (can be empty)
|
|
# SDLGLES_LIBRARY - library for SDL gles (can be empty)
|
|
|
|
# Types:
|
|
# Native - support is in SDL, program only needs to add SDL_OPENGLES flag to SDL_SetVideoMode
|
|
# EGL - support using directly EGL library, see http://pandorawiki.org/Combining_OpenGL_ES_1.1_and_SDL_to_create_a_window_on_the_Pandora
|
|
# program needs to initialize EGL and GLES manually
