I have to go look up all kinds of things whether I'm using Rust, Cpp, or python.
The package manifest for rust projects isn't as straightforward as some imply, but yeah, better than cmake!
However the comparison isn't totally fair. When building a cmake project, it's muscle memory to go `cmake ..` out of source, then do it again and tab complete to choose the build options. That's 99% of the work I have to do when pulling dependencies.
If you want a turnkey package build, just use vcpkg for Cpp. And guess what, it'll sit right on top of cmake.
What TFA is talking about is a 5% or less workflow: making a new package from scratch when you don't have internet connectivity or don't have a bespoke cmakelists.txt to reference. Makes for a nice blog post, but that's not a common dev workflow.
