CCS/66AK2H14: how to include driver code to our own created application project

Part Number:66AK2H14

Tool/software: Code Composer Studio

Hi,

I am using 66AK2H14 processor with TI-RTOS/SYS-BIOS using CCSV7 tool.

I created my own application code as required by the client, for that I had to include driver file. So when I include driver file using  "#include", I got fatal error.

c:\ti\pdk_k2hk_4_0_6\packages\ti\drv\gpio\soc\gpio_soc.h:45:30: fatal error: ti/drv/gpio/GPIO.h: No such file or directory
#include <ti/drv/gpio/GPIO.h>

I request you to tell me the procedure to include driver code to our own created application project as soon as possible.
