Code wise this looks like that:

#ifndef QT_NO_DEBUG_OUTPUT
QDebug akDebug();
#else
inline QNoDebug akDebug() {
    return QNoDebug();
}
#endif

Basically the same thing Qt is doing for qDebug().

Configurable logging requires some infrastructure, e.g. centrally accessible 
settings, which have not been available in Qt4 but are in Qt5.

One could potentially patch Akonadi Server with something primitive like a 
global variable, but that is unlikely to be accepted into the upstream code 
base.

The compile time switch is mostly there to have debug logging in developer 
builds and disable it in production builds (this has the advantage of not 
incurring any overhead).

Not entirely sure why it is built with that enabled when packages by 
distributions.

Cheers,
Kevin
