How to use qmake with -qtnamespace modified frameworks

[eric_vi]

i have qtnamespace modified framework and a qt project that works fine with it...

i am using
qmake -spec macx-xcode myproj.pro

to move my project toward xcode... when compiling the xcode project does not seem to take into account the new namespace...
does anyone knows what needs to be added and where so that can work

Thank you for your help
