Can't disable JPG support

@abma great, I will test when I get home :) A side question, do you know how I disable ex. jpeg support? I tried cmake -DIL_NO_JPG=1 but it still links with libjpeg. I need to include DevIL at a static library, and so I want to reduce the amount of library I need to compile static.

It still seems to link:

so I'm wondering if something is broken in the cmake script.
