1、Windows环境使用VS2017编译opencv-4.2.0和opencv_contrib-4.2.0源码，支持TBB_人工智能_$firecat的代码足迹$-CSDN博客.html（https://blog.csdn.net/libaineu2004/article/details/104252289）
编译的源码是 opencv_contrib-4.2.0.zip，使用的源码是 opencv-4.2.0.zip。这里使用的源码 都是 github下载下来的源码，并非 opencv-4.2.0-vc14_vc15.exe安装之后 里面带的source里面的代码...
没有下载 TBB（加速编译速度的，我无所谓了，就没弄这个东西）
2、编译过程中，说缺少一些文件，于是 到 "E:OpenCV_somethingopencv_contrib-4.2.0uild_zzCMakeDownloadLog.txt"中去看，是这些文件：
2.1、我第二次重新 用CMAKE config了一下，∵设置了 hosts文件，∴CMAKE开始自己下载 文件了 下的好慢啊... 而且貌似 还是有没有下载下来的文件，我需要手动下载一下...
