Lots of programming languages have their own package manager, separate from the distribution or OS package manager.

Going loosely from the TIOBE index:

  • Python has Pip
  • C# has NuGet
  • Javascript has npm for Node.js
  • Visual Basic also uses NuGet
  • R has a repository of packages that can be installed by running install.packages("something") in R
  • Rust has Cargo/Crates
  • Go has the go get command
  • Swift has its own package manager swift package
  • Ruby has RubyGems
  • Java has Maven and Gradle (not sure if they are full package managers, or build automation tools with dependency resolution)
  • PHP has Composer for managing libraries and dependencies
  • C and C++ are the only exceptions I can think of, off the top of my head; libraries are managed by, and coupled to, the operating system

It's not that it's a bad idea, it's more that it's basically impossible at this point.

Bazel can't use Cargo, CMake and so on for downloading & building packages because it is trying to do cross-language builds the right way - a single build graph that includes everything. No other third party package managers/build tools actually exposed their build graphs - only commands to perform builds, which are too coarse for Bazel.

To put it simply, its necessary if you are doing things at the scale of Bazel.
