So, in a perfect world, (where everyone uses CMake :-)  ) this would not 
be a problem.  Because cmake will automatically chain the dependent 
libraries.  The user only has to specifiy -lchicken and cmake will add 
the -lpcre.   You can put .o files into the list of sources for a cmake 
target.   I suppose you could get something that would only build the 
stuff twice, once for shared and once for static.   And use 
target_depends to make sure things are built in the right order...
