Self-answering, here's a proposed solution:
1. Create a Windows "system" environment variable on the PC, called PICOTOOL_OVERRIDE_DIR and set to (say) C:/development/pico/win_tools/picotool if you have a folder C:/development/pico/win_tools/picotool which contains the picotool.exe file that you desire to be used.
2. Edit the pico-sdk\tools\FindPicotool.cmake file, and insert the following, near the top of the file, immediately after the cmake_minimum_required(VERSION 3.17) line:
Now everything works with the normal cmake -G "NMake Makefiles" .. command.
Then I did a build, and successfully saw the .uf2 file created.
I'll submit this as a PR, in case it gets accepted. It's not pretty, but at least it's benign if that PICOTOOL_OVERRIDE_DIR system env var is not set, so it shouldn't break anything for anyone who doesn't wish to use this override method.
