Thanks Nathan for reply.

Thanks for suggesting symlink :)
I am looking for some option with clang-tidy such that $ clang-tidy --config-file-path </some/path/to/.clang-tidy> -- pick '.clang-tidy' from custom location not from parent(s) directories for a file name.

The `--config` command line option is specifying the config inplace that clang-tidy should use. Alot of the clang-tidy lit tests use this functionality, have a look at some tests files in `/clang-tools- extra/test/clang-tidy/checkers` for how this is done.
If that option isn't specified, clang-tidy will fall back to recursing the parent directories for a file name .clang-tidy and use that as its config, in much the same way that clang-format does.
I guess if you want to share a clang-tidy config across multiple projects your best bet is to symlink it to the root directory of each project
