You can use the %D% placeholder for the directory of the Makefile.am 
relative to the source directory. I can't find where I found out about 
it but it works. E.g., 
https://github.com/log4cplus/log4cplus/blob/master/src/Makefile.am. You 
can also generate the Makefile.am from a template using AutoGen to make 
things even easier.
