Help compiling Audacity 2.4.1 with ASIO support

Hi all,
I work on 64 bit Windows 10 Home edition, update 19041.329
I have been using Audacity for a few years for minor recordings/edits, and am now looking to use it for more professional music recordings, for which I would like to incorporate the ASIO capability. I have next to zero experience with programming, so I have really been tied up these past few days researching and experimenting with the many wonderful suggestions and advice I found here, blindly following instructions, and I have gotten stuck at one (?) particular point.
I have, to date:

Apparently I’m now supposed to open audacity.sln in VS, but I’ve searched hi and low, and it’s nowhere to be found!
Any clues? And can anyone tell me, ‘are we there yet?’
Thanks
YS

The build system for Audacity has recently changed to using cmake.
Currently there are no instructions for building with ASIO using cmake, and I’m not a Windows developer so I can’t help with that. Your best chance of success is probably with the Audacity 2.3.3 source code as that pre-dates the move to cmake.
