Subject: [PATCH] build: Only enable -Werror for debug builds
-Werror is very unhelpful for distributions and end users as newer
compilers will raise warnings that the maintainers may not see. The
warnings should get reported upstream, but they shouldn't block users
from using the software.
Rather than drop the flag entirely, I have enabled it only for debug
builds, e.g. -DCMAKE_BUILD_TYPE=Debug.
