In the event that a Makefile itself is changed, a safe bet would be to consider all targets out of date.
Is there a clever way to add this dependency? Are there any alternatives?

A Makefile rule that typically scans all C/C++ source files in a directory, and generates rules that indicate that an object file depends on certain header files, and must be recompiled if they are recompiled.
Makefile sets a set of rules to determine which parts of a program need to be recompile, and issues command to recompile them. Makefile is a way of automating software building procedure and other complex tasks with dependencies. Makefile contains: dependency rules, macros and suffix(or implicit) rules.
A simple makefile consists of “rules” with the following shape: target … : prerequisites … recipe … … A target is usually the name of a file that is generated by a program; examples of targets are executable or object files. A target can also be the name of an action to carry out, such as ' clean ' (see Phony Targets).
The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files.
Make sure the object files depend on the makefile:
$(OBJFILES) : Makefile Where Makefile is the name of the make file.
