This is the way things are done on Windows in general, supply your own libraries with your app, even if they are supposed to be "shared". For exactly that reason, no idea what the platform supplies, and no dependency management system. I think the situation is similar in Mac OS for anything other than OS standard libraries, there's no official Mac package manager with dependency tracking. So SecondLife style virtual world viewers (and likely some games) do exactly the same on Linux. Sure it's not needed as much, but A) the developers have to do it on those other platforms anyway, B) makes for easier support on the often least used platform if it's using the same damn libraries as the others. Similar on Android to actually. It's really only Unix's with proper package dependency management that can get away with actually sharing libraries properly, and that's not the mainstream. "Enterprise" Linux developers generally only write for Red Hat Pointy Hair Edition, sometimes it can be a pain to get that big end of town shit to work on anything else. Same issue (ABI not universal), different solution (just ignore the other distros). Personally I want to experiment with "see what libraries are available" at run time, do some quick tests on them, if they are not suitable, download a suitable one and don't share. I'm quite prepared to tell mainstream OS users that their OS sucks and they should install a real one, or more RAM. B-) -- A big old stinking pile of genius that no one wants coz there are too many silver coated monkeys in the world.
