qwtconfig.pri changes dont reflect in make for ARM

hi,

I am cross compilling qwt with qt 4.5.3. My problem is that whatever changes I made in the .pri file are not picked up by qmake for the -project option. I want to leave out the designer plugin,the svg renderer,etc from being compiled since they break the build and are not really essential anyways.

Is there any way to make sure qmake honors the changes in qwtconfig.pri?

Thanks,
Gautam
