Hmm, as we want to know where the packages that provide those files
were installed, and not where is Sugar installed, I think @prefix@ is
not what we want here.

The best I can think right now is harcoding to the /usr prefix, or
adding a configure switch for each. Unless we can get those paths from
a .pc file, which would be the ideal but I don't think it's likely.

What do other packages that consume those files?
