Explicitly tell clang-tidy where the config file is

joto · joto · commit 069724f10332 · 2025-08-22T19:32:13.000+02:00
For some reason clang-tidy will behave differently when run from
different current directories if the config file is not set explicitly.
It is supposed to find the source files to check in the
compile_commands.json file and find the config from there, but
apparently that is not the whole truth!?
