Static Library for STM32H753

I am trying to generate a static library which calls FreeRTOS functions listed below -

1. osThreadDef and osThreadCreate
2. osSignalSet and osSignalWait
3. osDelay
4. osMutexCreate

etc.

in System Workbench for STM32.

Without including the FreeRTOS Utility in the project, I get errors like,

           Type 'osThreadId' could not be resolved

           'osPriorityNormal' undeclared (first use in this function)

When I choose option to include the FreeRTOS Utility in the project, I get the same errors as above.
