From 7af6cbe74d48a9853b60b029d4ce38a963386138 Mon Sep 17 00:00:00 2001 From: Romain Naour Date: Sun, 3 Jul 2016 20:19:48 +0200 Subject: [PATCH] webrtc: C++11 is only required for WebRTC support Make C++11 support optional and explicitely check for gnu++11. Stop the build only if no C++11 support has been found and WebRTC support has been resquested.
