Error resolution-“Error in configuration process, project files may be invalid” appears when Cmake compiles openCV


error occurs when cmake compiles opencv

error paste as follows:

This is because FFMpeg did not download successfully
Open path E: \ Files \ openCV, openCV, sources, 3 rdparty \ ffmpeg \ ffmpeg cmake in the download address (openCV download address before half save position may be different)
here it is important to note that the download address to converted (yellow parts are replaced with another yellow box) box last green added to the end of the
as a convenience to see clearly, my download address as follows, slightly more than once to see:

In addition also need to know what the hash value of the three files downloaded: query tool https://download.csdn.net/download/xubuhui/12032166
tool to use: click the exe after installation to find need query file right click -> properties can see the corresponding MD5
