To be fair as an outsider to both Rust and Js they seem to have pretty robust package management between cargo and npm, although npm is kinda cheating as collating scripts isn't quite as complex building binaries whereas PIP's absolutely unberable with all the virtual env stuff.

I've been quite lucky with CMake, after the initial learning period I've found everything "just works" as it is quite well supported by modern libs.

Cargo and npm are very robust so long as you stick only to their respective ecosystems. However as soon as you need something from a different eco system they each become hard. The initial import into an ecosystem isn't hard, but the reimport after every update upstream is very annoying.
