Mine is a bit similar, also adds the syntax required to use a designer
generated ui file and resources. Pasted below. I tend to create an eclipse
makefile project to work with it (I don't even worry about the qt plugin as
this is like directly working with code anyway).

Not sure what you mean by importing multiple packages as a single project -
you mean the ability to build multiple qt programs in one ros package? I
haven't tried it yet, but the cmake qt macros should enable that following
similar calls as that given below.

I've also got a mate here who's starting to build a library of qt-opengl
widgets we can use as an ros library package. He tends to build them at a
much lower level though (no designer generated ui's), but follows a similar
approach.
