I see how some classes show this during compilation:
.... -I"d:\Qt\examples\designer\worldtimeclockplugin" -I"d:\Qt\qt\demos\gradients" -I"d:\Qt\qt\demos\shared" -I"d:\Qt\qt\demos\deform" ....

I dont want theese elements. I played with them but I dont understand what are going inside my proj.

Where I have to look ? Any idea ? Thanks.
