Updating Make Support Files

You should update a project's Make Support Files after you've made any structural changes to the project, or whenever you include additional files in its source files.
Note that SNiFF+ automatically updates the Macros Make Support File of a project when you do one of the following:

- add or remove files to or from the project
- add or remove subprojects to or from the project
- Modify any Make attribute of the project.
