[vtkusers] Max OSX ld: Undefined symbols: .objc_class_name_NSApplication

[Ravi Gupta]

Hi,

We are trying to build VTK 4 on OSX using cc and c++. After dealing with 
  including additional vtk files into the build we are left with the 
following error. We have found some files on the system with a NSxxxxx.h 
  name format but no .o (object files). We are not sure how to proceed 
to get the linker to find the relevant non vtk files.

Errors below and CmakeCache.txt attached.
