/*************************分割线*************************************************/
从GitHub上克隆的opencv_contrib，在make时出现错误。
克隆的opencv与opencv_contrib网址如下：
https://github.com/opencv/opencv
https://github.com/opencv/opencv_contrib

分割线以上就是错误代码。

但是我的【opencv/modules/festures2d/test】目录下已经有了【test_detectors_regression.impl.hpp】文件，是我的opencv或opencv_contrib目录放错了吗？
