Can you post an example?  We don't need to see the source file names.

I don't think it's possible for a target to set a variable.  Well, one
way you could do it (if you were the one writing the makefile, which you
aren't!) is with conditional expressions:

ifneq ($(filter magic_target,$(MAKECMDGOALS)),)
MAGIC_VARIABLE := 42
endif
magic_target:

This will set MAGIC_VARIABLE to 42 if magic_target is one of the targets
specified on the command line.
