OK. We should probably get the same to happen with cmake. What is the
command line used to link ./Debug+Asserts/bin/lldb? I assume the
relative path is being added by llvm's Makefile.rules. Is the absolute
one being added by lldb's?

Brand, is there a way to add to rpath from an inner CMakeLists.txt?
