Get QT Creator running with OpenGL ES2.0 using environment variables

[blissfreak]

Right now I'm on Windows, and I have a @$(GLES)@ environment variable setup, which I'm hoping to use with QT's QMake. I'd just specify the absolute path in the directory to this, but I'm working with other people on this project, and it makes sense if we use environment variables.

What I need is to figure out how to get OpenGLES2 in the include path, as well as how to link it in the QMake file. My Qmake looks as follows:

@HEADERS +=
VFTHandler.hpp
VertexFragmentHandler.hpp
util.hpp
ShaderHandler.hpp
ShaderComparable.hpp
Shader.hpp
SearchTree.hpp
pdmaths.hpp
JniShaderGlue.hpp
JniGlue.hpp
GraphicsView.hpp
GraphicsService.hpp
GlIncludes.hpp
FileUtility.hpp
Debug.hpp
Comparable.hpp

SOURCES +=
VFTHandler.cpp
util.cpp
ShaderHandler.cpp
ShaderComparable.cpp
Shader.cpp
SearchTree.inl
Main.cpp
FileUtility.cpp
EscSearchTree.cpp
Debug.cpp

LIBS += -L$(GLES)\lib -lEGL -lGLESv2
INCLUDEPATH += $(GLES)\include@

Note that this won't compile. Is there anything I can do with this, using environment variables? I am on windows, though a linux solution would be great as well in addition to this.

I use glew and setup my build like so:

@QT += opengl

win32|linux-g++|linux-g++-64 {
LIBS += -lGLEW
DEFINES += BUILD_DESKTOP USER_INTERACTION
message(Desktop build)
} else {
DEFINES += BUILD_DEVICE
message(Device build)
}@
