通用makefile

scons虽然简单且跨平台，但内部隐藏了太多细节。Make相对清爽些。

然而每次都写makefile有点嫌麻烦，网络上也流传很多通用makefile。今天特找来一个，分享之

all : $(DESTINATION)

deps : $(DEPS)
	$(CC) -MM -MMD $(SOURCE)


objs : $(OBJS)

clean :
	@$(RM) *.o
	@$(RM) *.d
	@$(RM) $(DESTINATION)

rebuild: clean all 

ifneq ($(MISSING_DEPS),)
$(MISSING_DEPS) :
	@$(RM) $(patsubst %.d,%.o,$@)
endif

-include $(DEPS)

$(DESTINATION) : $(OBJS)
	$(CC) -o $(DESTINATION) $(OBJS) $(addprefix -l,$(LIBS))

简单的Hello world之类的只需要填写DESTNATION即可。可应付大部分情况。
