I guess so. At least, I haven't heard of anyone planning to do it differently.

Yeah, but to be clear: just a header tree, not the full Boost distro.

IIUC, Marcus has already made the separate header-generation step obsolete, so
it now happens automatically if you have his changes, which are here:

Once you have Marcus' header generation, that would work perfectly. Until then,
it will probably work just fine, but you might have to explicitly build the
GenHeaders target if your library's set of header paths changes. You might want
to consider putting the individual include/ directories of the libraries on
which you're working
(e.g. https://github.com/boost-lib/filesystem/tree/master/include) in your
#include path ahead of the generated headers to avoid that I guess.
