It can also be one of a couple of 'special forms': @executable_path and
@loader_path.

Can/will cmake be able to support these forms?  For example, I'd like to
be able to build vtk as dylibs and then place said dylibs in my
application's bundle.  This means that the dylib's 'install_name' must
be "@executable_path/Contents/Frameworks/".

I also suggest that when cmake builds dylibs it always use the '-
headerpad_max_install_names' option so that the install_name can be
easily changed after the fact, if need be.  See the 'install_name_tool'
man page.

Thanks,
