Add explicitly the name of the LCIO libraries

• Add explicitly the names of the LCIO libraries to allow builds where the names of the libraries may not be known while configuring LCCD

ENDRELEASENOTES

It's unlikely LCIO libraries change a lot in the future and also it's maybe a better design to only link to what's needed.

[tmadlener]

Is this still relevant? Additionally, at last SIO should have a proper target name.

[jmcarcell]

Yes, this is still relevant. I don't get the SIO comment, is sio not a good name or are you referring to something else?

[tmadlener]

SIO exports proper CMake targets (SIO::sio) that could be used, rather than hardcoding the library names

[jmcarcell]

The only problem for that is that the SIO from LCIO doesn't have that but I've added it in iLCSoft/LCIO#176

[jmcarcell]

Change of plans: it turns out it was linking to SIO but SIO is not needed in LCCD so it's even easier

[jmcarcell]

PR updated to work with iLCSoft/LCIO#177

superseded by #10
