Andrew Schwartzmeyer created MESOS-8689:
-------------------------------------------
Summary: Add -Werror semantics to the CMake build
Key: MESOS-8689
URL: https://issues.apache.org/jira/browse/MESOS-8689
Project: Mesos
Issue Type: Improvement
Reporter: Andrew Schwartzmeyer
While MESOS-8658 got us to warning-parity with Autotools, we still don't have
-Werror turned on because we need to figure out precisely which it'll apply to.
Autotools adds it to {{MESOS_CPPFLAGS}} which are then included in almost all
targets under {{src}}, but when we tried the equivalent via
{{add_compile_options}} we had issues due to warnings from protobufs.
Ideally we turned it on using {{target_compile_options(foo PRIVATE)}} so that
it's not directory-wide nor inheritable; but that'll mean figuring out which
targets to turn it on for. We probably should turn it on for stout-tests,
libprocess, and libprocess-tests too, which the Autotools build does not yet do.
