how to include QtNetwork while cross compiling vlc for windows

view story

http://stackoverflow.com – I am modifying vlc source code and have added a few UI screens. I needed to use QtNetwork package where as by default vlc only has QtCore and QtGui packages. While compiling for Linux i modified the primary vlc configure.ac to include QtNetwork and it worked fine. But when i attempted to cross compile following the standard process, the configure steps fails i.e. ../extras/package/win32/configure.sh --host=i686-w64-mingw32 indicating failure to locate QtNetwork (HowTos)
