Setting up backrefs in your build system is straightforward once you understand the basic pattern: define a source list, then use backref notation to reference those files in compile or package rules. Start by declaring your sources as a variable, then use that variable elsewhere with a backref prefix like $(sources). This keeps your Makefile maintainable and avoids repeating file paths across multiple targets.
