[vtk-developers] problems with VTK python module installation on OSX (after a custom build)

Using VTK_USE_RPATH=ON and building with that change resulted in full
path specifications in the .so file, but the path is now specific to
build directory, not the installation directory. So, how do we set
CMAKE_BUILD_WITH_INSTALL_RPATH:BOOL=ON
FYI:
