Hi Zhouping,

those look exclusively like symbols from OpenGL:

Try adding "opengl32.lib" -- it is not part of VTK, but a system library 
parts of VTK depend on.  If you do not have CMake build the project 
files for you, but want to know about VTK's library dependencies, have a 
look at the file "lib/vtk-<VERSION>/VTKLibraryDepends.cmake" (relative 
to your VTK installation directory).


HTH,
