how can I fix this error I get when I try to build the GameLift Server SDK with msbuild? I followed the documentation exactly except for the difference that I use VS 2019, so instead of cmake -G "Visual Studio 15 2017 Win64" -DBUILD_FOR_UNREAL=1 .. cmake -G "Visual Studio 16 2019" -A x64 -DBUILD_FOR_UNREAL=1 .. https://docs.aws.amazon.com/gamelift/latest/developerguide/integration-engines-setup-unreal.html#integration-engines-setup-unreal-setup.
