Not sure where the original name came from, it's been like that for a
few years - it might have been my fault :-)

In Debian/Ubuntu libraries development headers, unversioned shared
object symlinks and static archives always ship in packages named
libfoo[api-ver]-dev. This is strictly enforced by policy. We have
libdpdk-dev for example.

Then, usually, pkg-config files follow the same naming convention, so
that if you want to build against libfoo-dev you use pkg-config libfoo.
This makes it nice and predictable.
But IIRC it's not enforced, and not universally followed.

Even just a symlink should work fine, at least it does with the pkg-
config I have on Debian. Should not cause issues on any implementation.
