Ooooh I do have qemu emulation enabled, that must be it, thanks! I'll
need to be careful about that, seems too easy to make a mistake.

Yeah, if we have this pattern often it sounds like a good idea.
However, better yet maybe could be to make the cmake build-system handle
it automagically. I see `PKG_CONFIG_EXECUTABLE' is part of cmake itself
so that might be OK?

Ha! That's pretty cool :-).
