[vtkusers] Vtk Patented Library?

[Alan Zhou]

Hi, I'm a newbie for VTK. I'm trying to use
vkMarchingbues class to generate isosurfaces. 
There is a linking error when I tried to compile the
project MSVC6++ generated by CMake: 

marchingcubes.obj : error LNK2001: unresolved external
symbol "__declspec(dllimport) public: static class
vtkMarchingCubes * __cdecl
vtkMarchingCubes::New(void)"
(__imp_?New at vtkMarchingCubes@@SAPAV1 at XZ)

I donn't know if I should install or generate the
patented library and how to do it if I need. 

Another problem is the CMake program I installed
doesn't have the options like VTK_USE_PATENTED as
shown on some illustration webpage. So I have to 
turn it on in CMakeCache.txt. I don't know if it is
the right way to do it. 

Thanks a lot. Need your help. 

Alan Zhou.
