cmake default configuration bugs

[Jeremy Whiting]

Hello,

I'm not subscribed to this list, so please cc me on any 
replies.  I found a bug in the cmake defaults in taglib.  
It seems that for some reason ASF and MP4 are turned off 
in the default config.  While this is rather simple to 
turn on locally, it's a pain to have to do it on every 
machine taglib is built on (and in turn to turn it on 
when distro packages are built at every distro...)  Could 
you please turn it on by default?

thanks,
Jeremy Whiting
