[vtkusers] C++ link error about vtkMarchingCubes

[dahuang]

vtkusers:

    I met with a problem relating to vtkMarchingCubes recently. And this problem has been reported by someone else(http://public.kitware.com/pipermail/vtkusers/2002-April.txt), but I haven't found an answer to it. Now I put it again, hoping the experts can give an explanation.
   
   The problem is:when compiling the file medical2.cxx(mentioned on Page 510 of the book "The Visualization Toolkit:An Object-Oriented Approach to 3D Graphics"), we need to use the header file vtkMarchingCubes.h, which is in the patented directory of VTK source. But after I have built the vtkPatented.lib using CMake and put it in the vtk40\lib\vtk directory, the compiler VC6.0 still reports the link error below(already set the Options->Directories and Project Settings->Link Page).
   
   Where does the problem lies?
