Details:
- create a sub directory to store CMake scripts (later more to come)
- add a search Ogre package script (may be replaced later by "official" Ogre 1.7 search script, since they switched to CMake, yeah !)
- fixed header issues being not available with MSVC and replaced by equivalent functions if assumed portable enough
- Removed CMakeLists for now. It's enough work to keep the
existing build alternatives updated. We can add it back later when
things stabilize.
