STM32H755 http server fsdata.c not detected in the build

Hi, I am having some problems with my stm32H755. I tried to make a http server without FREERTOS.

The problem is that my project doesn't build because fsdata.c is not found. I'm a bit lost because CubeMx generates the middleware file outside the M7 project I'm working on.

In Cube MX I just enable ethernet and LWIP on the M7 core. With httpd enabled in LWIP config.
