How to connect a logger like P7 or log4cpp to your application?

Question

Qt

I want to add a logger application in the owl with the output of logs to a file, I tried to add the loggers indicated in the header. I threw cpp files and headers into the project, but the compiler threw out more than five hundred errors, most likely I'm doing something completely wrong). Also, connecting a logger in this case requires adding more than a dozen source files.
