[vtkusers] vtkIterativeClosestPointTransform.h

Thanks Amy,
Had you replied a bit earlier, it would have spared me lots of banging my head with my machine :D You are absolutely right.Same was the problem and it is solved now.

Also, did you build VTK yourself? vtkIterativeClosestPointTransform is 
in VTK/Hybrid, and there used to be a CMake option for whether to build 
they Hybrid library (VTK_USE_HYBRID, I think). I don't remember if that 
was VTK 4.4, or if it was earlier than that.

If the vtkHybrid library was built in your copy of VTK, make sure you're 
including that library when you link your application.
