Standard Cell Library Integration

Hi, 

   New to Cadence tools and I am not sure how to integrate a PDK standard cell library into Virtuoso for schematic design and layout. I have the libraries imported and can view the symbol and schematic. I am using a IBM 0.18 PDK but the standard cells are broken into cdslib (Schematic and Symbol) and another directory tree with LEF, GDS, netlist, and Verilog files.  

I can not figure out how to link the libraries consisting of symbol and schematic views with the layout and additional views. 

I need some help here. 

Thanks!
