Since updates, my other comments here, and my own recent success, I should report that Visual Studio 2019 Community Edition, version 16.9.2, EasyBuild version 2.2.6, and CMake version 3.18, all on Windows 10 Pro 64-bit, I was able to build a MaNGOS core successfully, thanks to the great work of others!
The VS minor and patch versions were both very important to keep updated throughout, but may hopefully be less important now.
Perhaps you could show some step-by-step images of the installaion process. They seem to have changed quite a lot since 2015
