externals/hcs/hid/Makefile allows you do type things like:

make clean
make install

And it'll build [hid] and friends.  That Makefile calls externals/ 
Makefile so that I only have to maintain one.  That Makefile will  
also automatically set itself up if you stick into your CVS folder  
and there are targets of the same name in externals/Makefile.  You  
can also see the same file in action here:


and more...  But yes, this still depends on having packages/ 
Makefile.buildlayout, which is often erroneously referred to as "the  
whole directory layout".  In reality, in order to build the externals  
with the Pd-extended build system, you need:


That doesn't seem like much of a burden to me.  We've spent far more  
time discussing that pesty package/Makefile.buildlayout that it would  
have taken just to check it out wherever its needed.  That is not to  
say that improvements can't be made.  There is much that could be  
done, this is just the beginning.  I think that it might make sense  
to have all of a library's targets in its own local file, which then  
includes other global files for global things.  But that would take  
quite a bit of work to create.
