Subject: Use relative rpath so that the installation and build dirs are relocatable.
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=c94f3ae0278dc781cd60051790bf8a8003a13873;p=oota-llvm.git

Use relative rpath so that the installation and build dirs are relocatable.

This works by asking cmake to use the "install rpath", but setting that rpath
to be relative.

Thanks a lot to Brad King for the help with CMake!
