I ran the new version through various tests on my machine and these changes look good to go! Thanks for the pull request, @victorluft .

Not that big of a deal, but is there any reason why the new libGL inclusion here needs to be conditional...? Is it really likely that the version is ever going to be < 2000 after this is merged in? Even if it was it doesn't seem like it would cause a problem to have libGL included anyway?

Probably not; I figured there's a chance somebody might for some reason want to override with a previous version, but I'm happy to un-conditional it if preferred.

I can see the logic for allowing overrides if it was a library removal or something, but since it's just the addition of a new library it shouldn't prevent anyone from overriding without issues even without the conditional. I think it's best to keep the change simple and remove the conditional.

Makes sense. Done!
