🤔 I am unfamiliar with cpp libraries. Not sure, though sharing few resources (pdf / non-pdf) that might comes handy to you. Probably, you might have this references already 🤔

- changkun.de/modern-cpp/pdf/modern-cpp-tutorial-en-us.pdf [includes all c++ 11/14/17/20]

- modernescpp.com/index.php/the-c-standard-library-the-third-edition-includes-c-20

- stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list [complete cpp book guide]

- github.com/AnthonyCalandra/modern-cpp-features [includes features for c++ 20/17/14/11]

- c++ 17 => viva64.com/en/b/0533/

Hope, this helps you!
