Building on Windows 10: CMake error

Hi all,
Trying to build for the first time…
Following instructions in BUILDING.md for win10, getting next error on step 3 under ## Building on Windows ( 3. Press Configure ):

installed:
cmake: 3.20.6
python: 3.9.7
vs: 2019

any help would be appreciated.
Thanks!

For compiling help, join discord at: Audacity dev
Then ask your question in #windows under COMPILING AUDACITY

You seem to be promoting discord! What is wrong with answering a compilation issue under the compiling audacity section of the audacity forum?

Thar’s because it is Muse’s preferred channel - the advantage is that there you get the eyes of the developers (less so here).
