说明：

include $(DEPENDS)包含头文件依赖文件很多事是会导致反应慢和两次进入子目录问题

一个直接编译多个目录下文件的makefile

CC=g++
MAKE=make
AR=ar cr
RM=rm -rf

#CFLAGS+=-Wall

LIBPATH=-L../comm/libs3/libuv-1.x/.libs
        -L../comm/share/.lib
        -L../comm/libs/asio/.lib
        -L../comm/libs/db/.lib
        -L/usr/lib64/mysql

CFLAGS= -I./
        -I../comm/libs/utils
        -I../comm/libs3/mysql/include
        -I../comm/libs3
        -I../comm/libs3/libuv-1.x/include
        
LDFLAGS= $(LIBPATH) -lm -ldl -lpthread -luv -lmysqlclient        

SRCSCPP=$(wildcard ../comm/libs/asio/*.cpp)
        $(wildcard ../comm/libs/db/*.cpp)
        $(wildcard ../comm/share/*.cpp)
        $(wildcard sourcecmd/*.cpp)
        $(wildcard sourcedb/*.cpp)
        $(wildcard source/*.cpp)


OBJS=$(SRCSCPP:%.cpp=%.o) 

TARGET=test

all:$(TARGET) 


$(TARGET):$(OBJS)
    @$(CC) -o $(EXEPATH)/$@ $^ $(LDFLAGS)
    @echo create $@


%.o:%.cpp 
    @$(CC) -c $< -o $@ $(CFLAGS)
    @echo "Compile $<"


clean:
    @-$(RM) $(TARGET) $(OBJS) 

 头文件依赖关系另外的写法：

%.d:%.cpp
    $(GCC) -MM -MT "$*.o $*.d" $(INCS) $< >$@

文件排除

SRC := $(filter-out a.cpp b.cpp, $(SRC))

Make will set the special variable MAKECMDGOALS to the list of goals you specified on the command line. If no goals were given on the command line, this variable is empty. Note that this variable should be used only in special circumstances.
