I have a source library I'd like to include in my Boost.Build project. The library consists of an assortment of header and cpp files in a folder next to the main cpp file and jamfile. It doesn't require any elaborate precompilation, so it should work just by #including the appropriate header files in the main cpp file (i.e., #include "FolderName/FileName.h").

My question is, do I need to do anything other than that to make this work? I'm getting an "undefined symbols" error, so clearly Boost.Build not finding something correctly.
