配置win10+cuda10.1+CMake3.13.4+opencv4.1.0报错无法连接服务器

Couldn’t connect to server from the Internet.
Perhaps direct connections are not allowed in the current network.
To use proxy please check/specify these environment variables:
- http_proxy/https_proxy
- and/or HTTP_PROXY/HTTPS_PROXY

原因

因为缺乏相关组件，网络又下载不下来，所以generate一直爆红失败。

解决

找到对应缺的组件进行下载,并放进对应位置里：

opencv_contrib-4.1.0\modules\xfeatures2d\src

然后再在CMake里面进行Configure与generate就ok啦~
