I have been building my C++ app on the Mac, for the Mac. But soon I would like to be able to make this simple game available on multiple platforms. I got prematurely excited when I saw that Parallels has provided an extension to work with Visual Studio code on Mac. But a closer examination shows that this extension is only icing on the cake. What I can’t find anywhere is a “Take it from the top” document describing how I might cross-compile from Mac to Windows and run the product in a Parallels virtual machine that is running on the Mac.
