I never had any problem with using libraries packaged into distro repositories. And I don't want C++ package manager. From my experience with other languages, it would result in lots of low-quality and poorly maintained packages used instead of established standard libraries. On the other hand, it may be acceptable for "applications" world, as opposed to system software. Desktop applications may benefit from it, but first we need proper sandboxing to prevent low-quality libraries from undermining security.
