You can't use #ifndef QT_NO_OPENGL before including whatever is supposed
to define that. That's qconfig.h, included by qglobal.h.
Also, make sure that the desktop OpenGL code isn't activated when
compiling in OpenGL ES 2 mode -- QOpenGLFunctions_1_0_CoreBackend and
other classes aren't defined.

This commit adds part of the output of utils/glgen and some simple
modifications to QOpenGLContext to allow easy access to classes
containing functions specific to a given OpenGL context and version.
This allows compile-time detection of mis-use of OpenGL features.
For example, trying to use glBegin(GL_TRIANGLES) with an OpenGL 3.2
Core Profile context will be detected by the compiler rather than at
runtime.
These capabilities make it much easier to add functionality to Qt and
applications that relies upon core features of OpenGL from specific
versions e.g. geometry shaders.
