BUILD_ON_WINDOWS is an environmental variable you need to create. To do that, open Windows Explorer, right click on “This PC” or “My Computer” (depending on Windows version), click “Properties”, click “Advanced system settings”, click “Environment Variables…”, on the bottom half (“System variables” panel), click “New…”, type BUILD_ON_WINDOWS as “Variable name”, and 1 as “Variable value”, then click OK.
