How do you diagnose slow CI here?

[djaiswal12]

I've been looking at cross-platform CMake projects to understand how maintainers debug build time, and cannectivity has more CI surface than most; 4 workflows across Linux + Windows + Macos.

When a build gets noticeably slower, how do you work out which target is responsible? Do you dig into the Ninja log or CMake timings, or mostly go by feel and bisect?

Asking because I keep hitting this on my own native projects and I'm trying to figure out if there's a better way people have landed on. Happy to share what I learn across the projects I'm looking at.

I would suggest asking in the Zephyr Project instead, as CANnectivity is really just piggybacking on the build environment of Zephyr: https://github.com/zephyrproject-rtos/zephyr/
