There are two uses cases for package managers. One is as an end-user to install software, another as a developer to have a set of specific libraries to use. For the latter, the version used varies per project. The former is typically system wide. For my hobby projects, I indeed use cmake to generate .deb packages which I then use in other projects. For professional development I've never seen this work successfully.
