The meson stuff and the FreeBSD fixes can go in as-is, but I haven't had time to think through the path changes, hence the delay (they do look sensible at first glance though).

Oh, maybe I misunderstood what PackageIndex::dataPrefix() is supposed to return. I made it return a prefix value "/usr/local", which made adding "/share/" necessary in all those places. But maybe I'm wrong and it should just return "/usr/local/share"?

That was the original intent, but that actually would have caused a bunch of consistency issues, therefore I changed that assumption (and the surrounding documentation). But it looks like the changes weren't made everywhere, which is why your patch makes sense.

Sorry for the long delay, but I didn't have a single quiet minute over the past weeks to think through this. The changes are good to go :-)
