The reason it doesn't work in VTK 5.0 is because that was released
before CMake 2.4 so it does a big hack to prevent installation with any
kind of rpath enabled.  Also the default behavior for the release branch
is to have rpaths off.  Apply the attached patch to re-enable
installation with rpaths.  Then run

cmake ../VTK-5.0 \
  -DCMAKE_INSTALL_PREFIX=/sw \
  -DBUILD_SHARED_LIBS=ON \
  -DCMAKE_INSTALL_NAME_DIR:STRING=/sw/lib \
  -DVTK_USE_RPATH=ON

This should get it working for most of the libraries.  Then instead of
using -DCMAKE_INSTALL_NAME_DIR:STRING=/sw/lib you can add

SET(CMAKE_INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib)

to the source tree.  You may also need to use SET_TARGET_PROPERTIES to
tweak the setting for a few targets, but probably not.
