# AX_BOOST_BASE([MINIMUM-VERSION], [ACTION-IF-FOUND], [ACTION-IF-NOT-FOUND])
#
# DESCRIPTION
#
# Test for the Boost C++ libraries of a particular version (or newer)
#
# If no path to the installed boost library is given the macro searchs
# under /usr, /usr/local, /opt and /opt/local and evaluates the
# $BOOST_ROOT environment variable. Further documentation is available at
# <http://randspringer.de/boost/index.html>.

# This macro calls:
#
# AC_SUBST(BOOST_CPPFLAGS) / AC_SUBST(BOOST_LDFLAGS)
#
# And sets:

dnl are found, e.g. when only header-only libraries are installed!

# SYNOPSIS
#
# AX_BOOST_SYSTEM
#
# DESCRIPTION
#
# Test for System library from the Boost C++ libraries. The macro requires
# a preceding call to AX_BOOST_BASE. Further documentation is available at
# <http://randspringer.de/boost/index.html>.
#
# This macro calls:
#
# AC_SUBST(BOOST_SYSTEM_LIB)
#
# And sets:
#
# HAVE_BOOST_SYSTEM
