Most of the functionality we use in Boost, certainly. We have
features, variants, and can build multiple variants in build step. We
have regression testing support. The CMake-based system builds all of
the libraries, tools, and tests in Boost 1.34.1. It does some things
better than BBv2 (e.g., detecting zlib and bzip2 for use in
iostreams), some things that BBv2 can't do (my favorite: graphical
installers), but not everything has been ported over (e.g., no
BoostBook support).

It's about 8,000 lines of CMake, 4,700 of which are comments.

Here's the Boost.Thread library's description:

   barrier.cpp condition.cpp exceptions.cpp mutex.cpp once.cpp
   recursive_mutex.cpp thread.cpp tss_hooks.cpp tss_dll.cpp tss_pe.cpp
   tss.cpp xtime.cpp

The boost_add_library macro is described here:
