FindOpenGLES2
--------------
Find OpenGL ES headers and libraries.
Imported Targets
^^^^^^^^^^^^^^^^
``OpenGL::GLES``
The OpenGL ES library, if found.
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables in your project:
``OpenGLES2_FOUND``
true if (the requested version of) OpenGL ES is available.
``OpenGLES2_VERSION``
the version of the OpenGL ES library.
``OpenGLES2_API_VERSION``
the version of the OpenGL ES API, this may be different than OpenGLES2_VERSION.
``OpenGLES2_LIBRARIES``
the libraries to link against to use OpenGL ES.
``OpenGLES2_INCLUDE_DIRS``
where to find the OpenGL ES2 headers.
``OpenGLES2_COMPILE_OPTIONS`
this should be passed to target_compile_options(), if the
target is not used for linking.
