推荐答案

发生此错误是因为 cmake 是（a）不是安装或（b）不在用户的路径上。

This error happens because cmake is either (a) not installed or (b) not on the user's path.

在这种情况下，OP已经下载了 cmake gui应用程序来自cmake.org ，并将其复制到 / Applications 。此应用程序不会自动添加二进制文件的路径，这就是脚本无法找到 cmake 的原因。

In this case, the OP had downloaded the cmake gui application from cmake.org, and copied it to /Applications. This app doesn't add the path to the binaries automatically, which is why the script couldn't find cmake.

通过添加cmake二进制文件的路径（bash语法）：

By adding the path to the cmake binaries (bash syntax):

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

OP能够成功构建opencv。

the OP was able to successfully build opencv.

大多数包裹经理 - 例如自制软件或 macports 会自动为用户添加路径允许它运行而不必再修改路径的配置文件。

Most package managers - e.g. homebrew or macports whould have automatically added a path to the user's profile that would have permitted it to run without having to modify the path any more.
