Here is another idea plus explanation for the weird behavior:

I'm not really a big fan of powershell. Is there an image on appveyor which has git bash or similar installed? If not, would it be hard to install bash before the installation?

Yeah, I couldn't reproduce the error outside appveyor either.
This is why I had hoped that someone else had already generated user-config.jam 
files in appveyor.yml files, so I could simply learn from that experience, 
rather than stumbling around in the dark as I do now.

  You can avoid using user-config.jam for this
by setting the environmental variables,
variables for the other libraries).  It will
probably also work if you use
b2 ... include=%VCPKG%\include library-path=%VCPKG%\lib
although I don't think I've actually tested this.

OK, that seems to work fine indeed. Thanks !
