##### http:https://autoconf-archive.cryp.to/ax_boost_base.html
#
# SYNOPSIS
#
# AX_ROSE([MINIMUM-VERSION])
#
# DESCRIPTION
#
# Test for the ROSE C++ libraries of a particular version (or newer)
#
# If no path to the installed rose library is given the macro
# searchs under /usr, /usr/local, /opt and /opt/local and evaluates
# the $ROSE_ROOT environment variable. Further documentation is
# available at <http:https://randspringer.de/rose/index.html>.
#
# This macro calls:
#
# AC_SUBST(ROSE_CPPFLAGS) / AC_SUBST(ROSE_LDFLAGS)
#
# And sets:
#
# HAVE_ROSE
#
