You can, for all files *except* qconfig.h. You need to have separate qconfig.h as 
well as separate mkspecs/qconfig.pri, mkspecs/qmodule.pri, mkspecs/default. You 
usually use a separate qmake, but sharing that is possible provided the above 
restrictions are taken into account.

The easiest way to do all of that is to separate the Qt builds and headers 
entirely.

Note: there's no qmake option to search for the mkspecs/* files I mentioned. 
For qconfig.h, you can easily hack it. Linux distributions do that for Qt 4, by 
replacing qconfig.h with a dispatcher that looks like:

#ifdef __i386__
#  include "qconfig-i386.h"
#elif defined(__x86_64__))
#  include "qconfig-x86_64.h"
#
	...
#endif
