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
#]=======================================================================]
# Note that this doesn't try to find the gnutls-extra package.
