For example in Slicer3, we have VTK, ITK, KWWidgets, Modules, etc. It would be really cool if we could designate parts as independent modules and not do dependency checking when running special targets.

I think the idea that we have been thinking about, would be :

cd VTK
make  // this would only build VTK and lower depends 
cd VTK/Common  // this would only build vtkCommon and lower 

but
make vtkCommon // this would do all the depends.

We are sort of stuck with this one, they want local generate back.

We did, I think the entry is incorrect.  Alex, can you fix that?

A better command line interface would be good, the -D stuff is awkward at best.

>Anyway, good comments. Don't like the unsercmake idea... Whatever it does, we should do on the CMake level.

The post-processing is horrible, and we need to address the issues so the post processing
is stopped.
