Can I use the Sql Module without chanage .pro file?

My Case:

I use the MSVS 2005,QT 4.2.2

I set the "Project Property"->"Configuration Properties"->"NMAKE":

Build Command:
qmake -project //because the file count or file name maybe chanag.
qmake
nmake /f Makefile.Debug

but I want use the sql module........//this shoud add "QT += sql " to .pro file.

so ........... Can I use the Sql Module without chanage .pro file?
