Well, I managed to compile OIS, OISConsole Demo, and OISActionMap (Ogre Demo) via codeblocks.
Of course, there are some gotchas right now:
OIS does not install to /usr/local/lib when using the CodeBlocks project. It builds to ois/libs/
Since, to install to the usr directory, you need root privledges, and I don't know if CodeBlocks would ask :/
Anyway, this means that the local demos link directly to the ois/lib/OIS.so location. Which, is fine, I suppose.
Also, with the ./bootstrap, ./configure, make, make install..
Everything builds and runs fine. With the codeblocks generated binary demos (Ogre/CEGUI), you have to tweak your ld cache (via /etc/ld.so.conf and ldconfig) for the binary to find the shared Ogre and CEGUI libs... Not sure why. Anyway, the make install way is probably preferred way to do it.. But, I like having an IDE, so I will probably be using the new CodeBlock project mostly on linux now

I'll commit the changes, and it will be in OIS 0.7.0
