Re: [Boost-build] How to declare 3rd party libraries in the project-root.jam?

You might like to consider changing:
         <source>/site-config//log4cxx
to something like
         <source>log4cxx
as the site-config part is only relevant when the declarations are in 
site-config.jam and I think because of the following lines:
project.initialize $(__name__) ;
project site-config ;
