https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: dev-util/ignition-cmake-2.14.0 adds -Werror flag on its own. Discovered on: amd64 (internal ref: dash_tinderbox) NOTE: (DASH-SYSTEM) in the summary means that the bug was found on a machine that runs /bin/sh as dash but this bug MAY or MAY NOT BE related to dash. -Werror is not recommended for releases and should always be disabled when encountered in build-logs, because there are numerous cases where this breaks without purpose.
