Only OpenGL ES (OpenGLES.framework) is available on iOS. Furthermore, iOS
builds use the frameworks installed in the platform directory. On my system
that's
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks
or
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/Frameworks
for simulator builds. Both directories contain OpenGLES.framework but no
OpenGL.framework.
