QMake Change qmake output folders (debug/release)

Hi, im building my project with Qt Creator and i cant find a way to avoid the /debug and /release folders that qmake is generating.

i used DESTDIR to output my files, but somehow qmake is still craeting the debug and release folders empty. I 've seen that the resulting makefiles have this line :

SUBTARGETS = \
debug \
release

I wonder where can i change this configuration, since i dont want any of these folders.

Heres my .pro:

Code:
