Look into `extra-cmake-modules`

[ISSOtm]

https://api.kde.org/ecm/ provides some modules that could be interesting for us, like the ECMEnableSanitizers module. (Possibly there's more neat stuff to be found there?)

I have seen another project (kdab/hostspot) include it with find_package(ECM 1.0.0 NO_MODULE REQUIRED), and I'm curious as to why NO_MODULE is there, but whatever.
