I currently maintain a legacy C+ app that runs on x86/x86_64/armhf linux, all 4 android archs and x86/x86_64 windows.
The linux compilation phase takes 1m, whereas on windows (using MinGW) it takes 10m. It’s not the end of the world, but would the MS compiler be faster? Better?
You could also cross compile for windows from linux, iirc there are mingw packages on linux.
