# - Try to find the GNU Transport Layer Security library (gnutls)
#
# Once done this will define
#
#  GNUTLS_FOUND - System has gnutls
#  GNUTLS_INCLUDE_DIR - The gnutls include directory
#  GNUTLS_LIBRARIES - The libraries needed to use gnutls
#  GNUTLS_DEFINITIONS - Compiler switches required for using gnutls
