In the Fink package which uses cmake-2.0.5, there is the following cmake
command line option

   -DCMAKE_SHARED_LINKER_FLAGS:STRING="-L%p/lib -install_name
%p/lib/vtk/\`basename <TARGET>\`"

Here %p/lib/vtk is the directory where the libraries will be installed.
This hack works, but it does not work with newer versions of cmake.

I would be interested, too, if someone found out how to transmit the 
-install_name to the latest version of cmake. One can, of course, change 
the install_name after the fact by running install_name_tool on all of 
the vtk binaries and libs, but this is not a good solution.
