Projects tab

In the Referenced C/C++ Projects list, you can set project dependencies for the new project. In the list of other projects in the Workbench, you can select one or more projects that the new project will depend on. Initially, no projects will be selected.

Common wizards: C/C++ Projects; Projects tab

Setting project dependencies on the Projects tab.

For example, if you associate myProject with mySubProject, the IDE builds mySubProject first, followed by your project (myProject). If you change mySubProject, the IDE doesn't automatically rebuild myProject.
