How can I easily change preferences defined in a .prf file?
The file features/win32/default_pre.prf has rtti_off set by default. How can I change this behaviour from my project file? The .prf file seems to overwrite anything I put there.
Thanks for the help.
As long as you set things after the .prf files have been processed your .pro file should override them. It can be tricky though since in some cases a .pro file can be processed up to 3 times by qmake.
As a last resort you could just edit the .prf file in question.
