Use CMake command to move and rename for portability. Closes #73.

- Revert back CMake version. Use CMake -Wno-dev option to suppress the policy warning for CMake 2.8.12 early adopter.
- Since the new policy is not in place, set some more target property to prevent Urho3D static dependency libs from being transitively link to other targets linking to Urho3D.
