说明

bash 和sh有些差别，bash更强，支持[[]]
原作者 : Shunli Guo
Usage : ./gen_cmake.sh PRO_NAME EXE_NAME
Description : 创建一个cmake的工程
输入参数 ：PRO_NAME EXE_NAME 即工程名和可执行文件名
默认情况下运行本程序，会生成如下目录和文件

 test
 ├── build
 ├── CMakeLists.txt
 ├── config.json
 ├── include
 ├── lib
 ├── test
 │   └── main.cc
 └── version.h.in

其中：
1. CMakeLists.txt是CMake的描述文件
2. build是编译目录
3. config.json是配置文件
4. include文件夹是头文件搜索路径
5. lib文件夹是库文件搜索路径
6. main.cc是主程序

编译操作过程：

 cd build 
 cmake ..
 make
