Makefile: Efficient way to make all '.c' files depend on a header file with the same name?

As far as I know this should suffice.

%.o: %.c %.h common.h
\tgcc -c $<

\t is a tab, and the gcc -c $< is of course just an example.

OBJECTS = $(patsubst %.c,%.o,$(wildcard *.c))
%.o: %.c %.h common.h
    gcc -c $< -o $@

libfoo.a: $(OBJECTS)
    ar rcs $@ $^
