new folder specified by FILENAME is not created

[yalov]

In win10, if FILENAME in the global configuration file .conf is a file inside some folder:

FILENAME = "log/name.txt"

and folder doesn't exist yet, then the folder and the file is not created.

if I create folder manually, logging file is created properly.

std::filesystem::create_directory("log");
START_EASYLOGGINGPP(argc, argv);
