[vtkusers] building MATLAB MEX files with vtk 6.1?

[Meehan, Bernard]

I'd much rather do this in cmake - I do have the "Mastering CMake" book
(haven't yet mastered it, or mex for that matter).

I think that the first problem I was having with the mex script was that
the libraries needed to be specified with the version numbers?
This seemed to get farther:
#!/bin/sh
MEX=/Applications/MATLAB_R2013b.app/bin/mex
$MEX -largeArrayDims \
     -I/Users/meehanbt/VTK/include/vtk-6.1/ \
     hello.cxx \
     -L/Users/meehanbt/VTK/lib/ \
     -lvtkCommonCore-6.1 \
     -lvtkCommonDataModel-6.1 \
     -lvtkRenderingCore-6.1 \
     -lvtkRenderingOpenGL-6.1 \
     -lvtkRenderingFreeTypeOpenGL-6.1 \
     -lvtkInteractionStyle-6.1



Which gave this error:
Undefined symbols for architecture x86_64:
  "vtkSphereSource::New()", referenced from:
      _mexFunction in hello.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see
invocation)

    mex: link of ' "hello.mexmaci64"' failed.
