[vtkusers] building MATLAB MEX files with vtk 6.1?

[David Gobbi]

Also, though this is slightly off-topic, I'd also like to point out that it is
possible (and not very difficult) to build mex files with cmake without
using mex at all. After all, "mex" is just a shell script that calls the
compiler.  Cmake can do that and a whole lot more.
