I would say they are making it very inconvenient, but still not
forcing you. Push comes to shove, you can still build depend on a
specific version, and use an explicit -L.
Yes, it means you have to track where upstream puts stuff, and
manually upgrade. Yes, it is more prone to error. Yes, using pkg-config
is _convenient_. Yews, it is probably advisable to use pkg-config. But
not mandatory.
But the same argument can be used for using bison and flex, to
avoid writing your own parsers -- the tools make life easier.
I still think if your ./debian/rules calls a program, and that
is not in Build-essential; it is your responsibility to arrange for it
to be available using a build dependency.
