# - Try to find OpenGL ES
# Once done this will define
#  
#  OPENGLES_FOUND        - system has OpenGL ES
#  OPENGLES_EGL_FOUND    - system has EGL
#  OPENGLES_LIBRARIES    - Link these to use OpenGL ES and EGL
#   
# If you want to use just GL ES you can use these values
#  OPENGLES_GLES_LIBRARY - Path to OpenGL ES Library
#  OPENGLES_EGL_LIBRARY  - Path to EGL Library
