How to dynamically generate Makefile targets

Say I have a few files named foo.c, bar.c, baz.c, ... I want to create a Makefile target for each one that runs a build task.

foo:
  make foo.c
.PHONY: foo

foo.c:
  run build foo

bar:
  make bar.c
.PHONY: bar

bar.c:
  run build bar

...

I essentially just want to do make foo and it builds make foo.c. But I have x number of files and want to have make tasks for each. How to accomplish this. Something like:

FILES = $(foo bar baz ...)

$(FILES): $(FILES)
  make $(FILE)
.PHONY: $(FILE)

$(FILES).c: $(FILES)
  run build $(FILE)

But all the files are independent from each other.

You can use pattern rules for the .c targets and static pattern rules for the ones that have to be phony targets (i.e., foo and bar in your example):

targets := foo bar

.PHONY: $(targets)

# static pattern rule
$(targets): %:
   make $*.c

# pattern rule
%.c:
   run build $*
