dnl @synopsis AX_BOOST_PROGRAM_OPTIONS
dnl
dnl This macro checks to see if the Boost.ProgramOptions library is installed.
dnl It also attempts to guess the currect library name using several
dnl attempts. It tries to build the library name using a user supplied
dnl name or suffix and then just the raw library.
dnl
dnl If the library is found, HAVE_BOOST_PROGRAM_OPTIONS is defined and
dnl BOOST_THREAD_LIB is set to the name of the library.
dnl
dnl This macro calls AC_SUBST(BOOST_PROGRAM_OPTIONS_LIB).
