For a header-only library I'm maintaining the clang-tidy checks fail with warnings about c++17 features being used. This is most likely cause by clang-tidy assuming C++14 for the header files (since it's the default). Running clang-tidy manually with --extra-arg="-std=c++17" fixes (most) problems. You can the library at cda-tum/dd_package#104

Could you add a parameter to cpp-linter to pass along extra arguments to clang-tidy?
