The current behavior when the clang-tidy option is enabled is to attempt
to auto-fix the issues. This is not the best approach:
- It does not work for all the rules;
- It makes other warnings (not auto-fixable) difficult to spot.
This diff changes the behavior to cause clang-tidy to fail the build
when an issue is encountered, by promoting the warnings to errors. This
will prevent the user from missing a warning which is not auto-fixed.
Note: this option could be set in the .clang-tidy configuration file,
but it seems to have a bug and enable all the checks which is not the
