Shared components work brilliantly in a fantasy world where nothing uses new features of a library or depends on bug fixes in new versions of a library, and no library ever has releases with regressions or updates that change the API. That’s not the case, though, so often there’ll exist no single version of a dependency that makes all the software on your machine actually compile and be minimally buggy. If you’re lucky, downstream packagers will make different packages for different versions of things they know cause this kind of problem so they can be installed side by side, or maintain a collection of patches to create a version that makes everything work even though no actual release would, but sometimes they do things like remove version range checks from CMake so things build, but don’t even end up running.
