Sorry, spoke too soon. Building `clang-tidy` still has a lot of problems. The first one is the following but there are too many to copy them here.

```
ld.lld: error: undefined symbol: clang::ast_matchers::MatchFinder::addDynamicMatcher(clang::ast_matchers::internal::DynTypedMatcher const&, clang::ast_matchers::MatchFinder::MatchCallback*)
>>> referenced by QueryCheck.cpp:123 (/usr/local/google/home/ingomueller/git/llvm-project/clang-tools-extra/clang-tidy/custom/QueryCheck.cpp:123)
>>>               tools/clang/tools/extra/clang-tidy/custom/CMakeFiles/obj.clangTidyCustomModule.dir/QueryCheck.cpp.o:(clang::tidy::custom::QueryCheck::registerMatchers(clang::ast_matchers::MatchFinder*))
```

Did you try to build with `BUILD_SHARED_LIB`?
