From 653db8b938166db7833135f615b90c38a3f27a30 Mon Sep 17 00:00:00 2001 From: "Maxin B. John" Date: Thu, 25 Apr 2024 10:51:02 +0200 Subject: [PATCH] configure: Add option to enable/disable libnfnetlink Default behavior (autodetecting) does not change, but specifying either option would explicitly disable or enable libnfnetlink support, and if the library is not found in the latter case, ./configure will error out.
