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/

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

编译：

[root@okk msgpack-c-cpp-2.1.]# cmake .

[root@okk msgpack-c-cpp-2.1.]# make

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

[root@okk msgpack-c-cpp-2.1.]# cmake .

举个栗子：

                cmake -DCMAKE_INSTALL_PREFIX=$INS_PATH

                make

                make install
