思路：分为根makefile和各个文件夹下的rules.mak文件组成。
TARGET=libmid.a
#
#增加目录

SRC :=
obj-y :=
subdir-y :=
subdir-y += $(MID_PATH)/mid_main
subdir-y += $(MID_PATH)/mid_app

VPATH += $(moddir-y)
include $(patsubst %, %/rules.mak, $(subdir-y))
OBJ := $(obj-f)
OBJ += $(obj-y)
SRC += $(patsubst %.o, %.c, $(OBJ))
xtar:$(mod-y)
-$(AR) xv $<
$(TARGET): xtar $(OBJ)
-rm $@
$(AR) rcv $@ $(OBJ)
$(AR) ruv $@ $(filter-out $(OBJ),*.o)
clean:
-rm -f $(TARGET) *.o .depend
.PHONY:all clean $(TARGET)
BROWSER_DIR :=
obj-y += mid_browser.o
ifeq "$(USE)" "__TEST__"
BROWSER_DIR += $(MID_PATH)/mid_browser/mid_browser_test
subdir-y += $(BROWSER_DIR)
include $(patsubst %, %/rules.mak, $(BROWSER_DIR)) /* 其下又是一个目录，可以递归 */
