how to use Civetweb Digest Authentication without filesystem

[SumitNandi-eaton]

I am trying to use civetweb for webserver on a stm32 nucleo board with no filesystem.

w.r.t the civetweb example at https://github.com/zephyrproject-rtos/civetweb/tree/zephyr/examples/embedded_c
i tired using the AuthStartHandler but getting build error because
of dependency of the following api on filesystem

mg_check_digest_access_authentication(struct mg_connection *conn,
                                      const char *realm,
                                      const char *filename)

Is there a way to implement civetweb webserver with zephyr w/o using filesystem support?
