Face Detection Demo Program - Includes

Hi, 

After setting all the software tools (CCS v6.1, SYS/BIOS, etc) and testing the C674x LCDK platform  with a SYS/BIOS program now I want to run the "Face Detection" demo project.

I imported the project within CCS. When building the project, I am getting two errors: (1) could not open source file "i2c.h"; and (2) could not open source file "psc.h" as shown in figure 1. 

Figure 1

Searching in my computer I found the following source file versions (shown in Figure 2 and Figure 3 within red rectangles). 

Figure 2.- I2c.h files

Figure 3.- psc.h files

I have two questions:

1.- Which ones are the proper files to include in the face detection demo project?

2.- Is the "CCS Build --> Include Options" the best way to add the path to the corresponding folders?  

Regards,
