Hi,

Is it currently possible to nest a complete, seperately compilable
project inside a boost.build project. Say I have a library, foo, that
can be seperately compiled using boost.build. I use a "externals"
facility to get a given revision of foo into a nested externals or
vendor folder under a project that uses foo.

<~/dev/bar>
   + jamroot.jam
   + src
   |  + jamfile.jam
   |  + *.cpp
   |  - *.hpp
   - externals
      - foo
         + jamroot.jam
         - src
            + jamfile.jam
            + *.cpp
            - *.hpp

How would you do this with Boost.Build? I tried the naïve approach and
get bitten by an error along the lines of "warning: rulename
$($(project).attributes).get expands to empty string".

Ideas?

 /Brian
