Xcode not searching @rpath for dylibs?

In my Xcode project, I have several dynamic libraries that I built with a prefix of "@rpath/lib". I added a "copy files" build phase that includes these dylibs. They are installed to a folder called lib in Frameworks. I also set a Runpath Search path of "@loader_path/../Frameworks" which should be substituted as @rpath when the executable runs. DLYD looks at my binary's runpath which I examine using tool -l command on the binary. This produces:

Load command 47
          cmd LC_RPATH
      cmdsize 40
         path @loader_path/../Frameworks (offset 12)

So I assume that when my binary runs, DLYD will resolve the path the lib folder via the MACH-O binary.

When I run my project, I use Activity Monitor to examine the files the binary has open. I don't see my dynamic libraries being referenced from @loaderpath/../Frameworks/lib where they reside, instead I see them being referenced from /usr/local/lib.

What Xcode settings do I set so my dynamic libraries are properly found? I used the User-Defined build setting 'DYLD_PRINT_BINDINGS' to see what is linking, and I don't see my libraries being linked even though they are eventually linked against the libraries in /usr/local/lib

I have found the script I developed a while back which I used to copy .dylibs into the .app's Framework directory and detect dependent libraries, fixing the library references using install_name_tool. This should be set as a post-build script.

https://github.com/trojanfoe/xcodedevtools/blob/master/copy_dylibs.py

I haven't tested it for a while. The repo also contains the script I now use to bump build numbers, as per this question of mine.
