Isn't it inconsistent to have the version set as 4.8.0, for example,
if this is not the version included in Qt-4.8.0?

Also, if a developer wants to identify which webkit he's using, he'll
look at the soname of the library. If libQtWebKit-4.8.0 is actually
qtwebkit-2.1 and libQtWebKit-4.9.0 is qtwebkit-2.2 but the latest
version of Qt is, say, 4.7.2, he'll be *really* confuse. It'll be even
worse in a few years after Qt-4.8 and Qt-4.9 are released.

At least on linux, I would consider it messy to have the soname
(technical version) not in sync with the release/documented version.
It would be bad to have a "release numbers translation table", even
worse to have versions resembling the original Qt versions.
