If a custom config is going to be used, maybe it would be good to tune it a bit, since we are at the beginning of using cmake files. For example I would suggest a longer `line_width`, 80 was (maybe still is) for code to be easily seen on the very old terminal/console, but considering the current displays as well as terminal apps, it could be more convenient to have it like 120 or so. Otherwise we may end up in splitting lines/strings that are maybe not very long, but they are impacted by indentation.
