Sometimes Kciad complains about pins not being driven while during the electrical rules check, like in the example below:

This happens when pins are connected to a power network that has no explicit power pin. For example, I use screw terminals to connect a 12V supply to a PCB, therefore I have to add an extra label to the screw terminal so KiCad understands where the power is coming from:
