How can I use MATLAB Code Generation Based on TI C2000 DriverLib Library?

I have just started to use C2000 blockset for code generation. When I opened the project in CCS, I found the code is not based on driverlib.lib. I want to generate the code based on driverlib library. However, I do not know what should I do? Is there any specific setting for using driverlib?

In some website, they recomended Install Support Package (Embedded Coder Support Package for Texas Instruments C2000 Processors). However, it is not available for installation.
