Antoine Pitrou commented on ARROW-16778:
----------------------------------------
Instead of disabling warnings one-by-one, you can change the
{{BUILD_WARNING_LEVEL}} CMake variable. I don't know why we are not documenting
it ([~kou] do you know?), but it is described thusly in
{{cmake_modules/SetupCxxFlags.cmake}}:
{code}
# BUILD_WARNING_LEVEL add warning/error compiler flags. The possible values are
# - PRODUCTION: Build with `-Wall` but do not add `-Werror`, so warnings do not
# halt the build.
# - CHECKIN: Build with `-Wall` and `-Wextra`. Also, add `-Werror` in debug
mode
# so that any important warnings fail the build.
# - EVERYTHING: Like `CHECKIN`, but possible extra flags depending on the
# compiler, including `-Wextra`, `-Weverything`, `-pedantic`.
# This is the most aggressive warning level.
# Defaults BUILD_WARNING_LEVEL to `CHECKIN`, unless CMAKE_BUILD_TYPE is
# `RELEASE`, then it will default to `PRODUCTION`. The goal of defaulting to
# `CHECKIN` is to avoid friction with long response time from CI.
