Redirect stdout and stderr to log file?

[guilletrejo]

I know there is an option to redirect the logs to the Standard Output, but I don't see the reverse case.
There are times when you use an API of another library that does not use easylogging, and instead writes its logs to stdout and stderr.

I would like to be able to redirect those logs to the log file of my application to have everything in one place. Is this possible already? Or is it something to implement?

Thanks!
