As noted above, I tried both the variable names.  In fact, I have now even 
stripped out the "APPLE" if:

SET(INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib")
SET(CMAKE_INSTALL_NAME_DIR "${CMAKE_INSTALL_PREFIX}/lib")

I don't see either of these set in CMakeCache.txt after cmake is run.

Unfortunately, all I have is the massive behemoth of mysql.  I'm not really 
sure how to translate your example above into their sprawling build bits. 
:/  I will try again with all the RPATH pieces pulled as well.
