When BlueBerry is disabled, POCO is still being build. This seems unnecessary.
I'm not sure if this could/should be fixed. Other modules could use Poco. Or we declare it as deprecated and couple it to the BlueBerry switch. For me the second option would be ok. But then we should probably "hide" it from non-BlueBerry modules.
We can also put this on WONTFIX and wait for the new buildsystem ;)
