I do not think there is any such variable as VTK_LIBRARIES.  Where did 
you see an example or documentation of its use?  A variable like 
VTK_LIBRARIES does not make sense because only a subset of VTK's 
libraries may be needed by a project.  Variables like FOO_LIBRARIES 
exist for outside projects not built by CMake where dependencies among 
libraries are not known.

Yes, you should list the individual libraries like vtkIO or vtkRendering 
in the linking command.  List only the libraries that you use.  CMake 
will automatically link to the libraries on which the VTK libraries depend.
