Hello,

I hope my issue isnt wrong to mention here, but I dont know where to ask.
My current project is about an MCU who is collecting data to SPIFF and creats soft AP for downloading the data from SPIFF via smartphone.
Now some parts are successfully done. For html / css / java part I want to look through the project:

https://www.codeproject.com/Articles/5300719/ESP32-WEB-Server-with-Asynchronous-...

From the begining my first error was 
undefined reference to mbedtls_md5_starts

I found kind of solution in:
https://techoverflow.net/2022/08/06/how-to-fix-espasyncwebserver-undefined-refer...

and changed the mentioned forked libs
AsyncTCP
ESPAsyncWebServer
as described in the solution link above.

Fore the purpose not to affect other projects in my arduino directory, I created a src-FOLDER and did the include this way

#include "src/ESPAsyncWebServer/src/ESPAsyncWebServer.h"

Now its telling me 
xtensa-esp32-elf-g++*: error: ESPAsyncWebServer\AsyncEventSource.cpp.o: No such file or directory

But it is   

Can somebody help me with this issue please?
Appreciate any help and many thanks in advance,
Christoph from austria
