Dynamic Libraries in Xcode

I am trying to create a mac application in Xcode that has some implementation in a dynamic library.

I added a new target (dynamic library) to my Xcode cocoa project and after a battle battle with frameworks and precompiled headers, compile dynlib and successfully execute the debugger.

When run offline, however, it is obvious that dynlib is in the wrong place. "Library not loaded: /usr/local/lib/testlib.dynlib." On Windows - my more ordinary platform - Dll can be placed in the same folder as exe, and anywhere on the path to the system.

I would prefer my application to look for its dynlib somewhere in its application package (and some documents seem to confirm this as the right approach), but I don't know how to do it.

Is it possible to configure the project in Xcode so that dylib is actually copied to the application package in the place where the application will look for it?

It seems I don't need to use otool to reset the search path. If I edit the Target Info -> Build -> Deployment -> Installation directory, I can change, from within Xcode, the path that dyld will look for for dylib. By default, for the new dynamic library project, the path was set to /usr/local/lib. Which I changed to ./- otool confirms that. / Is now where dyld will look for this particular dynamic module. Unfortunately. / does not seem to reference any directory in my application :(
