Mac Pro 安装 cmake，报错 Warning: cmake-3.5.2 already installed, it's just not linked

1、先安装 brew，参考文章：Mac Pro 安装 Homebrew 软件包管理工具

2、执行安装命令

brew install cmake

出现警告提示：

Warning: cmake-3.5.2 already installed, it's just not linked

3、国外网友也遇到这个问题：cmake-3.5.2 already installed, it's just not linked

解决方案：为 cmake 建立一个软连接

 $ ln -s /usr/local/Cellar/cmake/3.5.2/bin/cmake /usr/local/bin/cmake
 $ cmake --version
   cmake version 3.5.2
