In Linux, handling shared libraries is quite well standardized. There's ldconfig utility managing /etc/ld.so* files to configure exactly where the libraries may reside, and of course LD_LIBRARY_PATH to add special cases. Dynamic libraries are versioned, with the default symlinked to the latest version. (Okay, some libraries have goofed in not bumping the version number at the proper time, but that's another matter.) Applications are expected to adhere to this information, and not go out of their way to do something else.
How does this work, then?
Assume the user has a special module in $HOME/.myapp/lib/, which requires a number of libraries scattered all over, none of them in the expected places. If your application was executed with $HOME/.myapp/lib/ in LD_LIBRARY_PATH, the user only needs to add symlinks in $HOME/.myapp/lib/ to point to the wayward libraries.
Your application does nothing special. It uses just the library filenames without paths in the dlopen() call.
And please, do not write an application which dynamically edits those symlinks; it's just weird and suspect behaviour. I'd personally never use such a badly behaving application.
You could, however, write a separate configurator tool, which uses e.g. ldd, file and readelf tools with e.g. find, the user can use to locate the libraries and manage the needed symlinks. But I don't believe the users will actually need one.

libchartdir, the first library in the otool list, does not have an absolute path set. I have to set the DYLD_FALLBACK_LIBRARY_PATH to /opt/local/lib to let dyld find it at runtime.
What makes the other libraries installed under /opt/local/lib (QuantLib, boost) have their path recorded in the executable?
