Cross-compiling binaries for Windows is easier than building natively
For me SDK sizes are showstopper. Mingw packages are probably 100-200 Mb total. To build anything native one has to install Windows (20+Gb in modern version and then Visual Studio 40+Gb). Not so easy to fit it all on an SSD drive.Xcode also have this problem now. 8Gb for Xcode 7 is manageable. But why 70Gb for Xcode 11?
