clang-tidy not part of base

Hello all,

Recently deskutils/treesheets upstream introduced clang-tidy to cmake:
---
set(CMAKE_CXX_CLANG_TIDY clang-tidy
-checks=cppcoreguidelines-*,clang-analyzer-*,readability-*,performance-*,portability-*,concurrency-*,modernize-*)
---
https://github.com/aardappel/treesheets/blob/9131048804169c448ba61900935ff04acfb1e279/CMakeLists.txt#L63C13-L63C13

This causing build to fail because clang-tidy is not found.
What I found is that 13 and 14 doesn't ship this program but it is
available as clang-tidy{13,15} from llvm ports.

As workaround I comment it out.
Any sugestions on what to do, what to say to upstream?

Should this be a cmake debug option?

Thanks,
