我收到此错误请告诉我如何解决...

Answer 1

发生此错误的原因cmake是(a)未安装或(b)未在用户的路径上.

在这种情况下,OP 已从cmake.org下载了cmakegui应用程序,并将其复制到.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的原因./Applicationscmake

通过添加cmake二进制文件的路径(bash语法):

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

OP能够成功构建opencv.

大多数软件包管理器 - 例如自制软件或macports都会自动添加一条路径到用户的配置文件,这条路径允许它运行而不必再修改路径.

您可能需要安装 CMake

My-Mac: opencv$ brew install cmake
