qmake enviroment variables

[qtarian]

Hey guys,

I have done following steps :

- I downloaded "qt-everywhere-opensource-src-4.7.1.zip"
- I compiled it with mingw with gcc version 4.5.2
- I successfully compiled my first code.

- I suddenly wanted to rename the Qt directory to something else. At this step nothing worked !
- Using online resources I did "qmake -query" and I noticed that if I change the name of Qt installation nothing would work since the internal variables are set to that. I used "qmake -set <variable> <value>" to fix this and I set all variable I saw with "qmake -query" to the new directory (the new name) .

- I am not yet able to get "qmake" work
- when I do "qmake -query" I see the old and new environment variables listed.
- I tried to find out where these variables are saved, but so far nothing found. I guess they are somewhere encoded. in the qmake manual it says these variables are persistent ! so if they are persistent there should be a way to delete/set them.

To be more precise : "qmake" generates "Makefile" which contains include/lib paths. These paths are set using the environment variables of "qmake". The Include/Lib paths are still pointed to the old paths not the new ones I set ! That's why I could not compile my code again.

FYI : I could not compile my code that used "fstream" with the executable SDK provided by Qt since there are things broken in their mingw build. so I had/have to compile the Qt again
