Yes, it isn't great. But I did that because that's the build process
upstream recommends. :-( I will explore alternatives and get back to
you.

Sure, I'll make these synopsis and description changes (for both
libqmatrixclient and quaternion). In my opinion, upstream calling their
protocol "Matrix" is a somewhat poor choice. The word "Matrix" is easily
confused with many other things.
