Yes, you're expecting qmake to observe environment variables. It does not. 
Make honours and processes them, but that's run after qmake has finished 
running and has written the Makefile. Two separate and independent steps.

Yes.

You cannot with qmake. You need to either make the variable a pure qmake one 
by passing it on the qmake command-line instead of the environment, or you 
skip doing the qmake checks and rely on Make rules only.
