If you downloaded the KDEmultimedia package, or just the KMid package, to compile KMid you must run configure, then make and then, to install it, make install (most probably, as root).
I've included some examples that are installed in $dollar;KDEDIR/share/apps/kmid
If you run into any problem, don't hesitate to contact any of the KDE mailing list, or send a report directly to me.
