rpath issues (strigi is wrong on OSX)

[Benjamin Reed]

What does KDE do for the rpath stuff on OSX?  I'm having a hard time
figuring out what does what...

I ask because there are issues with Strigi and OSX, because cmake is
not setting a proper rpath on the libraries it creates:

 /usr/bin/ld: warning can't open dynamic library: libstreams.0.dylib
referenced from: /opt/kde4/lib/libstreamindexer.dylib (checking for
undefined symbols may be affected) (No such file or  directory, errno
= 2)

Should the rpath stuff be broken out into some other cmake module that
things like strigi and QCA2 can import so that things "just work" the
way they do for kdelibs and up?
