Was hoping someone else would field this question...

Have you been able to figure it out yet? What platform are you on?
I'm not much of a cmake expert, unfortunately.

Are you familiar with readelf -a ? Check out runpath and rpath, and
if the nuke libs dir is being compiled in or not.

I also know that cmake variables that affect the rpath are:
INSTALL_RPATH_USE_LINK_PATH
along with
CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES

(where the all directories
listed in CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES will be removed
from the install RPATH)
