I’ve been working on a project using Ninja as the build system, but I’ve encountered memory issues during the build process (Ninja kept eating all of the available memory no matter how much I increased it). I’m considering switching to a different build system like Unix Makefiles. However, I want to avoid rebuilding everything from scratch to save time and resources specially that I only have like 400 files left from more than 2000 originally. Is there a way to do this?

googled the issue, asked gemini and chatgpt, kept increasing memory until i got to 14GB for the VM (the laptop has 16).
