gabime/spdlog ? reverse-engineered prompt

Build me a fast C++ logging library that I can drop into my projects, with both a header only option and a compiled option. I want it to support easy logging to the console with colors, regular files, rotating files, daily files, and a way to plug in custom log outputs later. It should let me set log levels globally or per logger, change the message format, and use a nice formatting style with placeholders for values.

Please include thread safe logging, an optional async mode, and a way to keep recent debug messages in memory so I can dump them later if something goes wrong. It should also be easy to print binary data in a readable hex format. Make it work cleanly with CMake and include a few simple examples and tests so I can see how to use it. If you need to check current docs for best practices, go ahead and look them up online.
