# GnuTLS LIBGNUTLS_CHECK_CONFIG ([DEFAULT-ACTION]) # ---------------------------------------------------------- # Derived from libssh2.m4 # # Checks for GnuTLS library libgnutls. DEFAULT-ACTION is the string # yes or no to specify whether to default to --with-gnutls or # --without-gnutls. If not supplied, DEFAULT-ACTION is no. # # This macro #defines HAVE_GNUTLS if a required header files are # found, and sets @GNUTLS_LDFLAGS@, @GNUTLS_CFLAGS@ and @GNUTLS_LIBS@ # to the necessary values. # # Users may override the detected values by doing something like: # GNUTLS_LIBS="-lgnutls" GNUTLS_CFLAGS="-I/usr/myinclude" ./configure # # This macro is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
