The fix is completely reasonable! The bpf probe compilation seems broken because we still search this file into the source dir

[FedeDP]

@gnosek can you fix this?

[FedeDP]

/milestone 0.12.0

[FedeDP]

Could be moved to 0.11.0 if Grzeg's response is quick :D

[leogr]

Could we revamp this? 🤔

[FedeDP]

TODO for me: double check that this does not break driverkit builds.

Hi @gnosek and @FedeDP just kindly checking in on the status of this PR. When do you all think we should work on it? Thank you!

[FedeDP]

Well, for #1452 i wrote a patch for driverkit to let it build through CMake: falcosecurity/driverkit#302
Once that is merged, we have no more blockers (driverkit side) for this one.

[FedeDP]

Same goes for #1188 !

[incertum]

Thanks for providing an update @FedeDP 🙏
