I already spent some time to find a project that handles such cases, unlucky so
far. I often could see the use of pkg-config without a fallback.
The docs say: install pkg-config or die.
That is also an option for us, especially since pkg-config becomes standard
more and more. But of course, If we find an example how to implement that *-
prefix stuff in a proper and maintainable manner (easy to read and understand)
in configure.ac, that is the way to go.
I appreciate any help in finding an example.
Else we have to amend the documentation... I already made up a patch for the
docs, but I am willing to wait a while before I push it.
