You can set CMAKE_SKIP_RPATH in the advanced cache options to disable

Programs can be executed by adding their location to LD_LIBRARY_PATH.
Does this actually work on OS X? (Since he stated he was using
dylibs, which, afaik, are only on OS X or Darwin.) AFAIK, the full path
to the library is always included in dylibs and you can't turn it off.
(See http://developer.apple.com/releasenotes/DeveloperTools/dyld.html
near the bottom where it lists "no rpath support".)
What do you do in this case?
I'm actually in the middle of implementing this now. You can in fact
turn it off and make the system use DYLD_LIBRARY_PATH to find it. The
library is created with an "install_name" which is copied into targets
that link to it. This name can be a full path or just a name. If it is
the full path then that path is used. Otherwise the path is searched
relative to each entry in DYLD_LIBRARY_PATH.
Currently CMake sets the install_name to the full path of the library in
the build tree, or to just the name of the library if CMAKE_SKIP_RPATH
is on. I'm currently implementing changes to tweak the install_name
when the targets are installed.
