# LIBSSH2_CHECK_CONFIG ([DEFAULT-ACTION])
|
|
# ----------------------------------------------------------
|
|
#
|
|
# Checks for ssh2. DEFAULT-ACTION is the string yes or no to
|
|
# specify whether to default to --with-ssh2 or --without-ssh2.
|
|
# If not supplied, DEFAULT-ACTION is no.
|
|
#
|
|
# The minimal supported SSH2 library version is 1.0.0.
|
|
#
|
|
# This macro #defines HAVE_SSH2 if a required header files are
|
|
# found, and sets @SSH2_LDFLAGS@, @SSH2_CFLAGS@ and @SSH2_LIBS@
|
|
# to the necessary values.
|
|
#
|
|
# Users may override the detected values by doing something like:
|
|
# SSH2_LIBS="-lssh2" SSH2_CFLAGS="-I/usr/myinclude" ./configure
|
|
#
|
|
# This macro is distributed in the hope that it will be useful,
|
