Question

I\'m creating a static lib on Mac OS X for one of our customers, as well as a small cmd line app to test the static lib. The cmd line project has 2 extra library search paths, w

You often have multiple targets in a single project - for instance, you might have a framework project with a target for building as a dynamic .framework bundle, and a target for building a static lib. Or your app might have a target for building the app itself, and a target for building some helper command-line tool that it needs to install.

Wherever possible, I'd suggest changing settings at the highest level (in the project settings, and simultaneously changing debug & release configurations), and only customizing the target settings when necessary. Even better, move as many settings as possible into xcconfig files, which seem a much more explicit way of specifying your build setup.
