Where is StormLib_vs19.sln file?

[sethmachine]

I cannot find this file in the repo. Is it checked in somewhere? A search on GitHub doesn't show it: https://github.com/search?q=repo%3Aladislav-zezula%2FStormLib%20StormLib_vs19.sln&type=code

I am trying to build this for Windows using Visual Studio 2019. Most of the instructions don't seem to actually match what's in the GUI program either...
