Are we allowed to request apps that are free and open source, but do not have Windows binaries precompiled by the developer? If so, your platform could provide an amazing public service by becoming the only source of Windows binaries for such programs.
From that page, I'm able to download a binary of the game, so no need to build one.
[Edit] as you've removed the link, my comment doesn't make sense anymore.
In general, no we don't build from source ourselves.
Sorry about that, I didn't expect a quick reply and thought I could sneak in a ninja edit. I would provide a different example but there's no need, as you've adequately answered my question. Thanks!
