That is likely the source of the problem then. You typically use the 
.pro file to generate the visual studio project file. If whoever did 
this originally had a mistake in there or if someone has since 
introduced an inconsistency by manually editing the VS project file then 
you could end up with this type of problem where one configuration is 
trying to use the generated files for some other configuration - or is 
just picking up some completely stale file.

I would suggest fixing up the .pro file and regenerating your visual 
studio project file using qmake.

Cheers,

ps It was this hassle that convinced me to switch to qt-creator on 
windows as that just uses the .pro files to generate Makefiles directly. 
It even re-runs qmake for you when needed.
