[cctbxbb] Using cctbx as a C++ only library

Thanks so much for getting back to me so quickly.

100 seconds is certainly fine, especially given that this will only be
performed every once in a while.

I totally agree - if cherry picking is time consuming then it's not
worth it.  I just wondered if there was a quick way to strip out some
of the top level namespaces completely from the build dependencies.
The only real gain here would be to reduce the slightly daunting
filesize of the source bundle itself - but as I say this isn't a big
deal.

One other quick question that's quite important to my project: is
there a way to build a debug version cctbx? At the moment I'm having a
lot of problems due to mixing of release/debug CRTs (when I build my
code in debug).
