Build error 'WINAPI_PARTITION_GAMES' is not defined as a preprocessor macro

When trying to build from Github master - no local changes - I keep getting the error: ‘WINAPI_PARTITION_GAMES’ is not defined as a preprocessor macro, replacing with ‘0’ for ‘#if/#elif’

Googling reveals this was a bug marked as fixed a year ago Unreal Engine 4.25 Preview - #228 by VictorLerp

Is this a problem in the source, or is it potentially something in my local environment that’s causing it?

Resurrecting this post, as I’m also having this issue. Using the latest version of the master branch now is still giving me this issue. Been banging my head against a wall for a couple days at this point because of it…

Any luck with this?
