   I’ve received some feedback that replicating CI jobs locally isn’t straightforward. Perhaps the documentation can be improved in this area? @maflcko I understand you had some improvements in mind? Happy to also work on this.

   Yeah, this keeps coming up (ex: #31144 (comment)), but I don’t know how to improve the docs.

   Another related idea was to move the CC/CXX/SANITZER/… build options into a cmake preset, which could make it easier to reproduce some CI failures. Ref: https://bitcoin-irc.chaincode.com/bitcoin-core-dev/2024-09-05#1050658 and some more discussion in #30871 (comment)

   In the docs, it could be clearer to explain why env may be needed: #31176 (comment)
