Mats:

The point of convience libraries is that they only exist during
compilation, they NEVER get installed.  I've done a simialar project
using VPATH, but that has it's own problems.  I would suggest that
you create a convience library (you are using Automake, right?)
in each subdirectory, then link them into the library in the top
level directory.  This will work, so if you have problems read the
docs until you find the fix.  Once you get your head around how it
works you'll find Automake/Libtool makes your life much simpler.
