The variable is called CMAKE_INSTALL_NAME_DIR. The property must be set
using set_target_properties(). Also, remove all the other RPATH related
stuff, to avoid strange interactions. You might also want to create a
tiny test project for your experiments. E.g. something like this:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)
project(test)
set(CMAKE_INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib")
add_library(test SHARED test.c)
install(TARGETS test
  RUNTIME DESTINATION lib
  LIBRARY DESTINATION lib)

where the test.c file contains a trivial function, e.g.

void foo(void){}


Unfortunately I currently don't have access to OS X, so I wasn't able to
test the above...
