cannot find valid Visual Code Studio install

Hopefully this is the right place. Don't shoot me if it isn't, please.


I'm trying to build the JDK from Windows 10. I got so far as to 
configure failing on finding what it needs from the Visual Code Studio 
install via command line:


configure: Found Visual Studio installation at /cygdrive/c/Program Files 
(x86)/Microsoft Visual Studio/2019/Community using well-known name
configure: Warning: None of vc/bin/amd64/vcvars64.bat 
vc/bin/x86_amd64/vcvarsx86_amd64.bat 
VC/Auxiliary/Build/vcvarsx86_amd64.bat VC/Auxiliary/Build/vcvars64.bat 
were found, Visual Studio installation not recognized. Ignoring
configure: Found Visual Studio installation at /cygdrive/c/Program Files

vc/bin/x86_amd64/vcvarsx86_amd64.bat 
VC/Auxiliary/Build/vcvarsx86_amd64.bat VC/Auxiliary/Build/vcvars64.bat 
were found, Visual Studio installation not recognized. Ignoring
configure: Cannot locate a valid Visual Studio installation, checking 
current environment
checking for Visual Studio variables... not found
configure: Cannot locate a valid Visual Studio or Windows SDK 
installation on disk,
configure: nor is this script run from a Visual Studio command prompt.
configure: Try setting --with-tools-dir to the VC/bin directory within 
the VS installation


However there is no "bin" directory in this installation, at least not 
one that contains any of the specified files. This is Visual Code 2019 
Community, but I've tried the Professional version too. The building 
document doesn't specify which version, nor does it tell me how to fix this.


How do I get this to work via command line?
