You need to fix the errors relating to missing header files before doing anything. ---

The web page you link to says > There are two ways of using FreeRTOS in the Xilinx SDK environment then describes > Using a stand-alone BSP and > Using a FreeRTOS BSP .  These are the two methods that link the software project to the hardware description.
