make是一个命令工具，它解释Makefile 中的指令(应该说是规则)。在Makefile文件中描述了整个工程所有文件的编译顺序、编译规则。Makefile 有自己的书写格式、关键字、函数。像C 语言有自己的格式、关键字和函数一样。而且在Makefile 中可以使用系统shell所提供的任何命令来完成想要的工作。Makefile(在其它的系统上可能是另外的文件名)在绝大多数的IDE 开发环境中都在使用，已经成为一种工程的编译方法(Make is a command tool that explains instructions in Makefile. In the Makefile file, we describe the compilation sequence and Compilation Rules of all the files in the whole project. Makefile has its own writing format, keywords and functions. Like C, it has its own format, keywords and functions. And in Makefile, you can use any command provided by system shell to complete the job you want. Makefile, which may be another file name on other systems, is used in most IDE development environments. It has become a compilation method of engineering.)
