c - How use library at linux driver use linux source code tree to compile

Question

I want to modify the wifi driver of Linux, because I want use ioctl and socket to change the channel. So first I use a library to implement those function and install it to linux with the header file in /usr/local/include/ folder. For normal program, if I want to use this library all I need to do is add -llibaryname in the compile command. But since the driver uses Linux source code, it uses its own Makefile and uses the rule call Kbuild. I want to know how to modify the Makefile to let me use the library? Or is there are other way to reach my goal?
