cmake: Add defined so-version and public header to lib.

Adding a so-version means defining an ABI level. This level is decoupled from the ordinary version, even a major version change doesn't necessarily mean that the so-version should change (and thus have all dependencies to be rebuilt). Adding the public header to clarify the setup.
