Use <implicit-dependency>/boost//headers
I changed all the references in our project to use implicit-dependency and that works. It doesn't create the links, but I guess ./b2 headers is just something I will need to remember to do.
It's supposed to create the links and it seems to work within the Boost tree (for the most part--a few dependencies are missed).
I did some more experimenting, seems that I should be using more than just implicit-dependency as that will only indicate that the target may produce files that are included by the sources.
<implicit-dependency> will generate all the links that are found by the #include scanner. <dependency> will generate all links unconditionally.
Adding <dependency>/boost//headers causes the links to be generated, though I suspect the include path is being brought in my some other means because based on the description of the "features" it seems I should not put in <dependency> but instead <use> so the usage-requirements are brought across.
<dependency> gives you the usage requirements as well. <use> gives you the usage requirements, but does not add a dependency (i.e. <use>/boost//headers will add -Ipath/to/boost, but won't generate the headers. <dependency>/boost//headers will add -Ipath/to/boost and generate all the headers.).
