Makefile模板(改进)
Makefile模板：1) 模块文件(不含main函数) 分类存放于src/xxx目录下面。例如： src/conf/conf.c;src/util/pool.c
2) 公共头文件存放于 src/include目录，模块私有头文件放置于模块目录src/xxx目录下面
3) 所有的含有main入口点的源代码文件放置于src/目录下面，例如 src/main.c, src/test.c等。
4） 支持增加自定义目标，定义好自己的目标后就能够 编译出可执行文件(见模板最后示例). bin/main, bin/test等。
5) 支持依赖自动推导。
6) 使用时，请自行修改变量： CC、LINK、 SRC_FILE_TYPE、 MAIN_FILE、 SRC_MODULES、 LIBS、 INCLUDE_PATH 即可。
