Redis项目是通过make构建的，考虑到以下几点，我觉得有必要通过cmake脚本生成MakeFile
但是reids项目本身为了兼容跨平台性以及性能优化，提供了诸多的编译选项，我当前的cmake脚本只关注linux平台
1 项目结构
项目的构建分为两个部分
依赖的3rd_party编译，将其编译位链接库
源码，将其编译位可执行程序
2 make
之前看过了MakeFile的rule
3 cmake脚本编写
为了尽可能的简单，因此只关注于linux和mac平台，并且当前只编写了编译redis-server可执行程序的脚本
从MakeFile中可以看出来redis工程共提供了如下6个可执行程序的编译
redis-server
redis-sentinel
redis-check-rdb
redis-check-aof
redis-cli
redis-benchmark
3.1 根目录
3.1.1 CmakeLists.txt文件
负责源码的编译以及链接库
