Parts footprint list in Orcad Capture
OrCAD capture doesn't understand footprints (it's just a field that can be filled out as far as it is concerned). You have to manually enter a name that corresponds with the footprint name in your target layout suite of software. For instance if you are using OrCAD layout, make a list of the names of the likely footprints you may want to use from the layout library.

Other PCB suites will have a library you can interrogate but unfortunately there is no ability to browse a PCB library from layout in the basic form of layout.
