I don't want to talk about the reasons why I cpu-mine. It leads to nothing but arguments.
All I want to know is how to get cgminer to work without an openCl-device.
I'm being a bit of an eco freak there

, you can do what ever you want... but ck wont do anything to cpu support if not paid for so I guess the calculation is important even if your cpu does 25MH/s!
Without opencl it should just say that there is no opencl and still compile without oCL support, have you tried with opencl (sdk, etc) installed to your system? (even if you do not use it...)
