[vtkusers] Interacting with VTK under Mac OS X

[John Norris]

First of all, apparently just to keep things interesting, Mac OS X uses 
DYLD_LIBRARY_PATH, not LD_LIBRARY_PATH.

You can also try using the -install_name flag when building VTK.  Here's 
the relevant line from my CMakeCache.txt file.

CMAKE_SHARED_LINKER_FLAGS:STRING=-fPIC -undefined dynamic_lookup 
-multiply_defined suppress -install_name libvtk${KIT}.dylib

This builds the library without any built-in path (the default built-in 
path is wrong).  You could also hard-code in the install directory, and 
then you won't need to worry about DYLD_LIBRARY_PATH.

HTH,
John
