You did not specify where you what file.cpp to be placed. Assuming you want it
to end in 'Data', you can use this:

lib BVData : data other_source.cpp ;
cpp data : Data/file.bpy : <location>dir ;

This is likely to require development version of Boost.Build, that you can 
obtain from http://boost.org/boost-build2 (see the "Nightly build" link).
