The Project Options window, as shown in the following screenshot, can be accessed by selecting a project in the Solution pad, and then right-clicking it and choosing Options, or simply double-clicking the project. Alternately, go to Project | Project Options.
Under the General group, the Main pane is very similar to that of its Solution options counterpart. The only major difference is that at the Project level, you have the option to search for and automatically include new files when the project loads.
Unique to the Project Options dialog is the Makefile integration pane. Using this pane, you can add settings to synchronize file lists and references to variables in makefiles, plus you can invoke Makefile targets to perform builds.
