MAC下cmake安装

可以参考网上手动下载cmake的源码包进行安装，http://www.cmake.org/download/

解压后运行sudo ./bootstrap && sudo make && sudo make install

但是在执行./bootstrap的时候报以下错误：

/Users/baidu/cmake-3.9.0/Source/cmSystemTools.cxx:2061:39: error: expected ';' after expression
exe_dir = CMAKE_BOOTSTRAP_BINARY_DIR "/bin";

在网上找了好久也没有找到解决办法，遂决定采用brew来安装了。brew是个什么东东呢？其实就是linux系统下面的apt-get、yum神器。

安装brew只需要一条命令即可：

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

这就成了，brew就用下面3条命令即可：

搜索软件：brew search 软件名，如brew search wget

安装软件：brew install 软件名，如brew install wget

卸载软件：brew remove 软件名，如brew remove wget
