S = file1.c file2.c
O = $(S:%.c=%.o)

$(CC) ${LIBS} -o $<
# pull in dependency info for *existing* .o files
-include $(OBJS:.o=.d)
%.o: %.c $(CC) ${INCLUDES} $(CFLAGS) -MMD -o $@ -c $<
gcc -MM $(CFLAGS) $*.c > $*.d
.PHONY clean
clean:
\rm -rf *.o exe
Note: Green highlighted stuff optional or use -MMD, are used to create dependencies
Another Example:--------------------ERR = $(error found an error!)
.PHONY: err
err: ; $(ERR)
