Did you read:

http://boost.org/boost-build2/doc/html/bbv2/advanced/builtins/targets.html#id2549386

The second syntax does not only say "look in" c:/boost/lib, it also says that 
"lib1" is not built by V2, but is "searched". You'd need either:

lib boost : : <name>libboost<whatever_you_want> <search>c:/boost/lib ;
lib lib1 : $(SOURCES) boost ;

or if Boost is present in source form, directly use it:

lib lib1 : 
$(SOURCES) /some/path/libs/filesystem/build//libboost_filesystem ;
