CCS/PROCESSOR-SDK-C6747: Could not open source file soc_c6747

Part Number:PROCESSOR-SDK-C6747

Tool/software: Code Composer Studio

Hi

I have imported a project (already built) to my workspace but it seems not be able to compile it because I have the following error: 

fatal error #5: could not open source file "soc_C6747.h"

I have already installed the chip support library for C6747 that I found on this website  processors.wiki.ti.com/.../Chip_support_library

However, the named libray is still not "existing", therefore I can not compile the project. 

Is there any other way for adding this library?

Best Regards.
