I need to get the nth dependency file from a rule, something similar to $n in bash. I need this because I'd like to feed in individual dependency files as options to the build program.
Here's an example:
dep.o: dep.src config1.cfg config2.cfg
parse -cfg1 $2 -cfg2 $3 -o $@ $<
Is it possible?
dep.o: dep.src config1.cfg config2.cfg
@echo the second preq is $(word 2,$^), the third is $(word 3,$^)
