Please await eagerly - I have a lot of extensions to update. For over a decade I have been making tiny free extensions on assumption that they will require zero maintenance, but with 2.3 update, buffer_get/set_surface changes, changes to how extension macros work, and now x86 deprecation this is no longer the case.
As for building yourself, that’s not too hard for this specific extension - you set up Visual Studio (same steps as for the YYC guide), you open the .sln file, you pick Release - x64, and press Build. The compiled DLL gets copied over to different sample project folders.
