Description Alex Szpakowski 2015-07-30 00:13:10 UTC 
When SDL's CMake file is used on Windows, it sets the VIDEO_OPENGLES option to OFF even when ON is requested (which is the default.) As a result, SDL can't use OpenGL ES - including ANGLE - on Windows if it was built using its CMakeLists.txt file, since the necessary codepaths (e.g. all of SDL_windowsopengles.c) aren't compiled in.

When SDL is built using the Visual Studio project provided with SDL's source, the expected defines are enabled and OpenGL ES support works as expected.
