The thing is, for libraries (you mean .so?) you don’t have absolute paths, but only those relative to the bundle.
The install folder is, e.g., /my/build/folder/kicad.app/…
Everything inside the bundle is linked relative to kicad.app, so you can move the bundle everywhere.
The notion of a “install prefix” or where you “install” the bundle at build time doesn’t mean anything with bundles - it’s just a path you use at that moment in time, but maybe never again.

Sure, but if I just pick to install the app bundle to /my/build/folder (because this is my preferred folder to build in), then this has nothing to do with the place where the modules/footprints/etc. are stored (e.g., /Library/Application Support/kicad as one possible equivalent to /usr/local/share/kicad).

Sure, you could also do the switch here using #ifdefs.

Not quite for two reasons:
(1) KICAD_DATA points to the data location *inside* the bundle used for everything that is put *into* the bundle at build time. You don’t want to use that for modules/footprints/etc. because this folder won’t be seen for or changed by normal users (it is inside the bundle which is normally hidden).
(2) KICAD_DATA is the absolute path to where you have built the bundle - which is, as explained above, completely irrelevant. For OS X the equivalent of /usr/local/share is just /Library/Application Support (more or less, I might be wrong). This won’t change regardless of where the bundle is or the bundle has been built.
