在Mac上安装Cmake

在 Mac 上安装 PySide 的时候得到提示：

running install

running build

Python architecture is 64bit

error: Failed to find cmake. Please specify the path to cmake with --cmake parameter.

原因是没有安装 CMake。

去 https://cmake.org/download/ 下载了最新版，安装后发现并没有成功命令行安装。

打开 CMake ， Tools 里有一个选项为：How to install for Command Line Use. 

One may add CMake to the PATH:

PATH="/Applications/CMake.app/Contents/bin":"$PATH"

Or, to install symlinks to '/usr/local/bin', run:

sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install

Or, to install symlinks to another directory, run:

sudo "/Applications/CMake.app/Contents/bin/cmake-gui" --install=/path/to/bin

可以装 PySide了。
