[CMake] Linking Libraries

[abboti at rpi.edu]

I'll also add that the project compiles using MS Visual C++ with the
LINK_LIBRARIES removed (no reference to these VTKLibraries anywhere in
the top-level CMakeLists.

Adding each of the libraries to the TARGET_LINK_LIBRARIES, instead of
this LINK_LIBRARIES did not work.  This is the part that confuses me the
most.  
What LINK_LIBRARIES doing that TARGET_LINK_LIBRARIES is not?

So why don't you just add VTKCommon VTKIO VTKFiltering to the
appropriate TARGET_LINK_LIBRARIES commands?
