Right now, yes. And that's OK if you're already familiar with Boost (which
is not always the case). But my main objection was motivated by trying to
use dependencies outside Boost such as XML or cryptography libraries (I'd
love to see Boost.XML or Boost.Crypto but we can't wait for these). CMake
helps a lot here but it's easy to imagine that as the project grows the
install/upgrade procedure needs to be managed very carefully too. IMO,
libraries ought to be preferred to PCHs in this case.
As a side note, maybe I can advertise what I've started for the XMPP
client: http://github.com/glynos/cpp-netlib/tree/xmpp to let others know
what kind of issues I am facing, and maybe I ought to start a new discussion
to make progress on this.
