I have been able to compile the library as well as the example, no problem at all.
I also managed to compile my project by incorporating OIS in it and making my project depending on it. So, it seems that I was not linking to the lib (just linking to the precompiled library is not working, I don't know why...).
Anyway it's working and that's what really matter!
Thank you for your help, and all the great job you are doing developping OIS.
