Well,

I seem to have gotten further, but then ran into this:

CMake Error at CMakeLists.txt:91 (message): The PLATFORM environment
variable ([undefined]) doesn't match the generator platform (win64)

I notice that this page:

https://osqa-ask.wireshark.org/questions/56074/cmake-build-fails

discusses the problem and points to the document I was using, but that
document does not address the PLATFORM environment variable.

While it did not take long to figure the issue out, perhaps it could
be pre-empted by adding an additional environment variable to the list
in the documentation.


The Platform env. variable is set by vcvarsall.bat which is what's actually run to make a Command Prompt a "Visual Studio Command Prompt.  Setting it manually is NOT the correct thing to do.  It appears that there's still something wrong in your environment, as I noted on the Ask question you linked where the OP had a similar issue for reasons that were never resolved as they failed to respond.
  
As regards to my personal struggles, I just got Configuring done,
Generating done, Build files ...
