Make Module Error 2

Please do note i am relatively new to linux.
I am trying to install a driver for a wireless dongle D-Link DWA-182. I have a driver that works apparently for debian and ubuntu.
github.com/abperiasamy/rtl8812AU_8821AU_linux
I also installed DKMS
The first problem was when I run make I run into module error 2. I run uname -a to get 3.18.25 as my linux version. This is where I get stuck. When I do a cache search for linux-header I get 3.16.0-4 for headers. I installed the older header but I don’t know how to show make that I did my best.

If anyone needs any thing else please let me know I will try my best to provide.
Thanks in advance.
