To repeat, a configure script with msvc is about as useful as a bicycle 
is to a fish.

 From the root directory:

./bootstrap.sh

./b2 --with-libraryname

Will build "libraryname"

You would have discovered that with a :

./b2 --help

But.... Asio is header only, there *so is nothing to build*, likewise 
Xpressive.

./b2

Will build everything.

It *does* include everything that needs building in the default build 
process.
