e.g. if I fully build a target (call it "Target 1") and then do any of the following, XCode will do a full rebuild on the next compile.
1. Switch to Target 2 and then back to Target 1.
2. Add an executable or change the current executable.
3. Adding a file to the target, or to the project.
4. Dragging around an item in the group tree.
Sometimes changing a .cpp file in either the project or a dependency will also force a full rebuild.
We know one cause of this: if you a) have your Intermediates build directory inside your Project directory, and b) have a Header Search Path rooted at your project directory and recursive. After every build, Xcode notes that the contents of the build folder have changed (of course), and that your recursive search path depends on that directory, so it rebuilds headers.
Solution is to move the build folder out of your project folder, or specify your recursive search path more narrowly.
