4Subject: [PATCH] cmake: Disable nonnull-compare warning on gcc
5
6GCC finds a legit warning which clang does not on code like this
7
8class Message;
9void SendResponse(Message & aMessage)
10{
11    if ((&aMessage) != nullptr) { return; }
12}
13
14Perhaps it should be fixed upstream but for now disable treating this
15warning as error when using gcc
