opencv - 如何为iOS7构建OpenCV 2.4.8？

Question

我尝试重新启动我的EyeTracking系统。我知道已经有一些问题涉及同一个问题(How to compile OpenCV for iOS7 (arm64))，但是这些问题对我没有任何帮助。 github上的最新版本已经内置了所有arm64架构插件。因此，我不必更改python build_framwork.py。但是遵循OpenCV文档(http://docs.opencv.org/doc/tutorials/introduction/ios_install/ios_install.html#ios-installation)上框架的构建说明，会在终端中出现以下错误:

有人可以告诉我如何解决该问题吗？

sh: cmake: command not found

该项目使用 cmake进行构建，它是一个命令行实用程序。 cmake不作为Xcode 5工具的一部分包含在Mac OS X中-您需要自己安装它。 http://www.cmake.org/cmake/resources/software.html
