# mbed TLS (PolarSSL) LIBMBEDTLS_CHECK_CONFIG ([DEFAULT-ACTION])
# ----------------------------------------------------------
# Derived from libssh2.m4 written by
# Alexander Vladishev Oct-26-2009
# Dmitry Borovikov Feb-13-2010
#
# Checks for mbed TLS (PolarSSL) library libpolarssl. DEFAULT-ACTION is the
# string yes or no to specify whether to default to --with-mbedtls or
# --without-mbedtls. If not supplied, DEFAULT-ACTION is no.
#
# This macro #defines HAVE_POLARSSL if a required header files are
# found, and sets @MBEDTLS_LDFLAGS@, @MBEDTLS_CFLAGS@ and @MBEDTLS_LIBS@
# to the necessary values.
#
# Users may override the detected values by doing something like:
# MBEDTLS_LIBS="-lpolarssl" MBEDTLS_CFLAGS="-I/usr/myinclude" ./configure
#

# but WITHOUT ANY WARRANTY; without even the implied warranty of
