我得到这个错误请让我知道如何解决。 。 。

Answer 1

发生此错误是因为cmake （a）未安装或（b）不在用户的path上。

在这种情况下，OP 从cmake.org下载了cmake gui应用程序，并将其复制到/Applications 。 此应用程序不会自动添加二进制文件的path，这就是脚本无法findcmake 。

通过将path添加到cmake二进制文件（bash语法）：

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

OP能够成功地构buildopencv。

大多数软件包pipe理器（例如自制软件或MacPorts）都会自动添加一条path给用户的configuration文件，这样就可以在不需要修改path的情况下运行它。

Answer 2

您可能需要安装CMake

 My-Mac: opencv$ brew install cmake
