Ya me baje e instale la nueva version de Ogre SDK 1.4.5, y ahora si veo que ya existen la carpeta OIS y el archivo OIS.h y el resto de cosas antes preguntadas....
Pero ahora, tengo otro problema y es que cuando compilo o construyo me tira 4 errores, bueno la verdad son del mismo tipo
Aqui se los dejo

Si alguien me pudiera ayudar a resolver este error con OIS, se lo agradeceria
