I have now tested with the optional libraries. You need libzzip, libfreeimage, and libois. They all compile fine. The Ogre samples do not build correctly so you must prevent cmake from compiling them by adding -DOGRE_BUIILD_SAMPLES=0 to the cmake command.

Everything mostly works but there is some colour space problem (everything blue is orange) and some missing features due to using GLES and not GL.
