Yes, the DEPENDS argument that shows up in the module.cmake file needs
to list all of the libraries that this library depends on.

Right, so what Troy has done is to add a HEADERS argument to
boost_library_project that will be used to list all of the headers in
a project. One lists the top-level headers (e.g., signals.hpp) and any
directory names containing other headers (e.g., "signals"). That way,
we've identified which headers are part of the library and can
automatically move these into the right place as part of
"auto-modularization".

This is *exactly* what we're working on. At this point, we have enough
support for CMake so that users get a graphical installer on Mac and
Windows that allows them to choose which libraries to install
(including separate options for headers, specific library variants,
etc.), and the installers even encode the information from DEPENDS so
that you get a consistent installation. Select "any", and it'll
install type_traits, static_assert, mpi, etc. as well.

I'm going to have to punt to Troy on this one.

Yes.

We would appreciate the help. Our "TODO" list is here:
