I'm not trying to say your linearization circuit should be an IC. I have never used an LDR, but I have used thermisters, and for the ones I have used, the datasheet for the thermister explains how you should set up a resistor network for linearizing it over the specific temperature range you want to use. I was assuming the LDR datasheet would have something similar.
