Thanks, David.  I will give this a try.

Hi Aaron,

When you build VTK, or when you build your own programs against the VTK libraries, cmake bakes the load path into the libraries and the executables that it produces.  So in general, no paths have to be set.
 The run-time libraries will be found automatically.

CMake will strip out these baked-in library paths when you run a make install, so that the installed VTK programs will only search the system library paths, rather than searching your build directory for the libraries.  So if you install libraries to some location that is not in the system library path, then you will need to use DYLD_LIBRARY_PATH or some other path-setting mechanism.

More information (general info, not specific to OS X) is available on the wiki: http://www.cmake.org/Wiki/CMake_RPATH_handling

  David
