Hi, is there an article or a documentation for "getting started with incremental compilation" somewhere ?

What do you expect from this documentation? It’s really just enable it (it’s enabled by default btw) and hope it will work for your case

Is it written somewhere how to enable it ? I want to know how to have it enabled and how to optimize it depending on the machine, number of submodules etc

I don’t think that there is documentation about optimizing it. Submodules not even related to incremental compilation, but compilation avoidance

Okay I see, thanks I'll take a see

On this link you also can find link about build reports, which may help debugging issues with incremental compilation
