Fedora does not ship this library by default for patent reasons.
Not even the "s2tc" implementation? As far as I'm aware that one doesn't have known patent issues.
I don't know about s2tc, first time I hear that. A quick search seems to bring some legal question about potential inclusion: http://osdir.com/ml/fedora-legal-list/2016-05/msg00017.html
