[vtkusers] VTK and Qt, static build - CORRECTION

[Gib Bogle]

Sorry, I made a mistake.  I did 'make clean' and re-generated the make files 
with cmake, then did make again.  Now the VTK library files have the correct 
symbols (no "_imp___" prefixes).  I'm not sure what my mistake was before, 
probably not cleaning something.

Anyway, the problem with the app linker remains, many "undefined references" to 
  the VTK symbols prefixed by "_imp___".  Presumably I need a way to tell the 
IDE (which is QtCreator) to expect static versions of the library symbols.  I'm 
not sure whether this is a compile or a link issue.  I realize that this is now 
a Qt issue.

BTW this is all Windows with MinGW.
