clang-tidy -- how to exclude header files via regular expression

Greeting!

The feature to exclude certain headers (via regular expression), from generated warnings/errors, is much needed. Specifically needed for third-party sources for example: boost.

Can you pls suggest mechanism to exclude header files via regular expression with clang-tidy version 5, 6 or 7?

I found below references – but they are yet not available in GA releases!!!
