Hi Martin,

Unfortunately, it's more complicated than setting a switch.

Qmake's unix makefile generator has the ability to write pkg-config 
files. However, the win32 generator is used for building Qt for Windows, 
including when cross-building on unix, and this generator does not make 
pkg-config files. See qmake/generators/ in the Qt source tree.

Arguably, the unix makefile generator should be used to generate 
makefiles when cross-building, but in practice the win32 makefile 
generator is a better fit and its makefiles intended for mingw32-make or 
msys-make work just fine with gmake on unix.

If you are so inclined, you might try porting the pkg-config writing 
feature to the win32 generator. It probably makes more sense than making 
the unix generator suitable for cross-building for mingw on unix.
