Xcode dependencies across different build directories?

Question

I am trying to set up Xcode for a project which contains multiple executables and static libraries. I have created multiple targets and set up the linking and dependencies,

Answer 1

Xcode doesn't automatically set up dependencies based on use of build products; you have to set up explicit target dependencies yourself.

Project > Edit Target Settings, General tab, + button, add any targets that are prerequisites to building the selected target. That should get you going again.
