我目前正在尝试让 OpenCV 在 Linux（Ubuntu 16.04）上使用 OpenCV 额外模块（尤其是跟踪模块），cmake 3.5.1 我从https://opencv.org/releases.html下载了 OpenCV 的 3.4.5 版本和来自https://github.com/opencv/opencv_contrib/releases/tag/3.4.5的 OpenCV contrib 3.4.5 然后，我按照 OpenCV for Linux 官方文档的教程进行操作：https://docs.opencv。 org/3.4.5/d7/d9f/tutorial_linux_install.html
我在openCV上创建了一个构建目录并使用了命令
cmake -DOPENCV_EXTRA_MODULES_PATH=<openCV contrib/modules> <openCV source directory>
执行此命令后一切正常：

我没有错误
但是当我使用 opencv2/tracking.hpp 尝试使用文档中的代码时，我没有它。我只有 opencv2/video/tracking。如果我使用 opencv2/video/tracking在https://docs.opencv.org/3.4.5/d2/d0a/tutorial_introduction_to_tracker.html上运行代码，则 Tracker 未定义。
我应该如何重新安装 contrib 模块才能获得 opencv2/tracking.hpp？我尝试了许多版本的openCV，并阅读了许多教程......
谢谢
