I'm not sure if there is a length limit somewhere, but you can put more
or less everything there. quite many libraries from e.g. curret
kde-workspace has a libfoo.so.4abi4 version.

I still don't think there is a need.

This can just as easy be done by a script. the very simple:
#! /bin/sh
RELEASE_MAJOR=5
RELEASE_MINOR=3
RELEASE_PATCH=1
for i in frameworks/*/ 
do
  echo $RELEASE_MAJOR > $i/SOVERSION
  echo $RELEASE_MAJOR.$RELEASE_MINOR.$RELEASE_PATCH > $i/VERSION
done

and have a bit of cmake to parse these bits.

I'm also not sure we need shared installdirectories. Sure, most people
will put everything together, and we could even honour a
KDE_FRAMEWORKS_PREFIX env var for convenience.

Sure, this means clueless people can shoot themselves in their feet by
using a different prefix for each, building without RPATH and not
setting LD_LIBRARY_PATH nor any paths to cmake.

I basically find this a useless extra dependency imposed because we can,
not because we have any need for it.
