No. If we had a build system target for each library that installs its 
headers to the 'boost' directory before building we would be forced to
explicitly state the dependencies: (pseudocode)

# Boost.SmartPtr jamfile

synchronize sync_headers
   : [ glob-tree ../include/*.hpp ]
   : ../../boost
   ;

lib smart_ptr
   :
   : <dependency>sync_headers
   ;

# Boost.Filesystem jamfile

lib filesystem
   : [ glob-tree ../src/*.cpp ]
     /boost//system
     /boost//smart_ptr # NOTE
   ...
   ;
