[vtkusers] OSX universal binaires for VTK, cmake , ITK

[Mike Jackson]

Sean will chime in pretty quick but basically since CMake uses  
compilations to test things like endian then you run the risk of  
creating binaries that will not work. At the moment I build each type  
(PPC or Intel) on their respective machines then lipo them together  
on one of the machines. This is very labor intensive to do it this  
way but seems to be the only way to get the binaries to work right.

Sean may have more..
