I am working SWSTM32 (AC6 tool) Release 4.6.3 on STM32L4s5xx series controller.

I tried to add STM XCUBE MQTT stack to a base level driver code. The base level code has a folder CMSIS_RTOS and was compiled without any bugs, but when i add it is giving error as:- fatal error: ../Middlewares/Third_Party/FreeRTOS/Source/CMSIS_RTOS: No such file or directory
