Build error in CubeIDE. fatal error: lwipopts.h: No such file or directory

Hi

I cannot understand why my opt.h file cannot see the lwipopts.h file in the same folder.

Presumably, it must be something to do with the 'Wno-stringop-overflow' warning.

This contains a very long string -

 -mcpu=cortex-m7 -std=gnu11 -g3 -DUSE_HAL_DRIVER -DSTM32H743xxDUSE_STM32H7XX_NUCLEO_144_MB1364 -c -I../../../Src -I"D:/halfcontainer/projects/cubeideN/LwIP_HTTP_Server_Netconn_RTOS/SW4STM32/STM32H743ZI_Nucleo/Middlewares/LwIP" -I../../../Drivers.......+ about 200 chars-

Can anyone tell me how to find out whats happening?

Trying to look back at sys_arch.c is a bit frightening! (To me at least)

Thanks,

Chris
