# LIBNETSNMP_CHECK_CONFIG ([DEFAULT-ACTION])
# ----------------------------------------------------------
# Eugene Grigorjev <eugene@zabbix.com> Feb-02-2007
#
# Checks for net-snmp. DEFAULT-ACTION is the string yes or no to
# specify whether to default to --with-net-snmp or --without-net-snmp.
# If not supplied, DEFAULT-ACTION is no.
#
# This macro #defines HAVE_SNMP and HAVE_NETSNMP if a required header files is
# found, and sets @SNMP_LDFLAGS@ and @SNMP_CFLAGS@ to the necessary
# values.
#
# Users may override the detected values by doing something like:
# SNMP_LDFLAGS="-lsnmp" SNMP_CFLAGS="-I/usr/myinclude" ./configure
#
# This macro is distributed in the hope that it will be useful,
# but WITHOUT ANY WARRANTY; without even the implied warranty of
