# LIBSSH_CHECK_CONFIG ([DEFAULT-ACTION])
# ----------------------------------------------------------
#
# Checks for ssh. DEFAULT-ACTION is the string yes or no to
# specify whether to default to --with-ssh or --without-ssh.
# If not supplied, DEFAULT-ACTION is no.
#
# The minimal supported SSH library version is 0.6.0.
#
# This macro #defines HAVE_SSH if a required header files are
# found, and sets @SSH_LDFLAGS@, @SSH_CFLAGS@ and @SSH_LIBS@
# to the necessary values.
#
# Users may override the detected values by doing something like:
# SSH_LIBS="-lssh" SSH_CFLAGS="-I/usr/myinclude" ./configure
#
