[Qt-interest] Makefile rules in .pro file?

[Phil Dumont]

It's a bit kludgey, but adding this line:

!exists(myapp_gen.h): system(touch --reference myapp.ini myapp_gen.h; touch
myapp.ini)


anywhere before I add myapp_gen.h to the HEADERS variable stops qmake from
complaining and still makes the source generation script run on the first
make.
