The following libs (that should be on your system) are available:
- microchip_pic10mcu.lib
- microchip_pic12mcu.lib
- microchip_pic16mcu.lib
- microchip_pic18mcu.lib
- microchip_pic24mcu.lib
- microchip_pic32mcu.lib
They might not be added to your projects automatically. (Only a few of the “installed” libs are added by default.)
But they should exist in kicads system directory. (/usr/share/kicad/library under linux. somewhere under c:/ for windows.)
You can add them to your project manually. If you want them included in all your projects you have to add them to the default template. More details in this old thread:
