<pre>
My project uses clang-tidy with no issues. Recently I added to PQXX library (https://pqxx.org/libpqxx/) to connect to a Postgres database and since then clang-tidy fails.
I can confirm that simply including the library causes the failure, no matter what the code does with that library (even nothing).
Steps to reproduce:
1. Instal the PQXX library on the system
2. Add `#include <pqxx/pqxx>` to a .cpp file
3. Run `clang-tidy` on that file
