[vtkusers] find VTK library dependencies automatically

[Dr. X]

Hi All,

Would you please give me some hint on how to find out VTK library 
dependencies (automatically)?
When I build an application involving VTK, there are in general many 
libraries to be included. I don't quite know which library a particular 
VTK class belongs to. I am using CMake to create the build file.
Are there any tricks to let CMake automatically find VTK library 
dependencies and add them into the build file? Thanks a lot.
Best,
