Don't set warning levels by default #220
Description
Line 259 in c1d6146
Setting warning levels like those assumes that users are using the same compilers (and same versions thereof) as you are in your testing, and punishes users with spammy build logs if they're using newer compiler versions (which often come with new warnings!).
Ideally, warning levels for development purposes should instead be set in CI by setting the appropriate CXXFLAGS (probably along with -Werror) or locally by using appropriate tools like the new CMakePresets.json or equivalent.
