Generated Makefiles clean-up

[tora]

Hi,
I've compiled qt from the sources passing to configure some switches.
Now I want to get rid of this configuration and re-compile all passing this time to configure some other switches.
I've tried:
make confclean
but most of the Makefiles generated by configure the fist time was called remain there.
My question is: which target should I specify to make to get rid of all the generated Makefiles and go back to a "virgin" source tree?

** yes I'm a newbie: I post to the wrong sub-forum. I would be glad if some admin will move this thread in the Qt->Installation and Deployment sub-forum. Thanks ind advance and sorry **
