Review Request 66008: CMake: Enabled compiler warnings.
-----------------------------------------------------------

https://reviews.apache.org/r/66008/
-----------------------------------------------------------
Review request for mesos, Akash Gupta, Benjamin Bannier, Jeff Coffler, John Kordich, Joseph Wu, and Michael Park.
Bugs: MESOS-8658
https://issues.apache.org/jira/browse/MESOS-8658
Repository: mesos
Description
-------
We had previously been using the default sets of warnings, but now we
use the same warnings as on Autotools. This also means that we can
safely turn on the treat-warnings-as-errors (at least for the Mesos
code). However, doing so requires that we disable two common
possible-loss-of-data warnings on Windows that are not part of the
GNU/Clang default warnings.
This also replaces the use of `string(APPEND CMAKE_CXX_FLAGS)` with
the canonical command `add_compile_options` (though setting these on a
per-target basis would be even better, it's a separate issue).

Hm, then we should at least add it to `mesos-tests` too. I might right a function `ENABLE_WERROR(<target>)` to avoid duplicating this code over and over if we want to keep it private. Sound good?

Changes
-------
Addressed Benjamin's comment by making this a 1-1 mapping of the existing `-Werror` semantics. Instead of setting it as public compile option for `libmesos`, we set as a default compile option for the `src` directory recursively.

I'm sorry, I thought I had. It's [MESOS-8033](https://issues.apache.org/jira/browse/MESOS-8033). Adding to the review.
And this says `GLOBAL` because `add_compile_options` is a global-ish side-effect. It affects all targets from "this" directory downward (and while I don't like this design, and think we should fix it at some point, this configuration file is included in the top-level `CMakeLists.txt` file, making this essentially global).
Oh wait, I get what you were saying now. So, adding compile options per target instead of here (and below) is "a separate issue" because it's a design change. It's not something we necessarily have to or even should do; as these flags are set similarly to the old build system. It is generally in CMake more appropriate to set flags on a per-target basis, so my commit message was just calling out why we didn't do that. I'll amend it and make it more clear.

We definitely do not want to include `-Weverything` ever. It is intended for testing diagnostics by upstream developers, but would warn about issues we would not want to address (e.g., struct packing). You probably meant `-Wextra` like in the `GNU` case.

We should add a cmake configuration flag to disable `-Werror`. We have an equivalent configure flag `--disable-werror` since it is extremely unlikely that we'll support every possible setup (e.g., bleeding edge compilers, packaging setups). Let's give users a way to opt out.
