Error reason:
This error is caused by the incorrect setting of VTK_DATA_ROOT in CMAKE, which is the BUILD_TESTING option, and the need to download the VTKDATA data at compile time. The time to download the data exceeds the maximum waiting time set due to the network speed or lack of scientific Internet surfing.
Download the data and overwrite the MD5 file in the unzipper file \ExternalData\Objects\MD5 file in the binary directory.
