[skill][msgpack] 初试msgpack库以及基本使用

It‘s like JSON.   
but fast and small.

扩展阅读：

　　用到了Cmake ，大概是一个用来生成makefile的系统 ：https://cmake.org/overview/

　　https://zh.wikibooks.org/zh/CMake_%E5%85%A5%E9%96%80/%E8%BC%B8%E5%87%BA%E4%BD%8D%E7%BD%AE%E8%88%87%E5%AE%89%E8%A3%9D

release：

cpp-2.1.2

呃！ 搞了半天也不知道如何用git 把一个tag down下来。有点糗。。。。

直接download zip文件： file:///home/tong/Downloads/msgpack-c-cpp-2.1.2.zip

对应的文档：

编译：

[[email protected] msgpack-c-cpp-2.1.2]# cmake .
[[email protected] msgpack-c-cpp-2.1.2]# make

哇塞，竟然有进度百分比，我也要这样的makefile。0.0 -.-   ~O.O~
