  If you're passing this on the b2 command line, it won't work.
The include feature doesn't accept a semicolon separated
path.  You need to give a separate include=xxx option for
each path.

I have no idea what B2_INCLUDE is.

  You can set the environmental variables
ZLIB_INCLUDE / ZLIB_LIBRARY_PATH.  For more
options see
http://www.boost.org/build/doc/html/bbv2/reference/tools.html#bbv2.reference.tools.libraries.zlib

zlib and bzip2 are essentially similar.

  zlib and bzip2 are only used to enable the corresponding
filters in Boost.IOStreams.  If you aren't using these,
you can safely ignore them.
