What I am doing wrong or missing?

You appear to be missing a standard C++20 header. Does your compiler support C++20?

Hm, I used compiler packages provided by apt... on my raspberry/raspbian. How could I check it?

Same thing here on Raspbian GNU/Linux 10.

What file does #include <bit> look for. I've looked for bit.h in debian package search. Found it in Linux headers, but after installing that, it didn't solve the problem.

You appear to be missing a standard C++20 header. Does your compiler support C++20?

BTW, readme.md says "It also requires a modern C++17 compiler"
