Macos 如何重新编译opencv_traincascade（opencv 2.4）？

我想知道如何在macOS Sierra上只编译opencv_traincascade程序

我有traincascade的源代码（在/opencv-2.4.13/apps/traincascade/文件夹中）。但是，当我转到此文件夹并在终端上键入时：

cmake ..

它返回：

=>它不理解“ocv\u检查\u依赖项”

以下是CMakeLists.txt代码：

此外，这个问题在我的脑海中浮现，因为我在使用-featureType LBP的训练过程中陷入了困境。当我使用LBP功能训练面部检测器时，它显示：

为什么不编译所有库和工具（在基本目录中启动cmake）？这对我来说太花时间了。因为我只需要traincascade，所以培训整个库是浪费时间。编译整个库可能比搜索只编译tje工具的解决方案快得多。但是祝你好运！米卡：好的，兄弟，我试试这个方法。但是，我是通过Annaconda安装OpenCV的，我可以更改OpenCV的源代码（如上所述）并用Annaconda编译它们吗？为什么不编译所有库和工具（在基本目录中启动cmake）？这对我来说太花时间了。因为我只需要traincascade，所以培训整个库是浪费时间。编译整个库可能比搜索只编译tje工具的解决方案快得多。但是祝你好运！米卡：好的，兄弟，我试试这个方法。但是，我是通过Annaconda安装OpenCV的，我可以更改OpenCV的源代码（如上所述）并用Annaconda编译它们吗？
