Not use CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT
- CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT is widely used by users. But it seems not an offical variable of cmake since is does not appear on the cmake document. The problem is this variable does not work as we expect on Windows (we use it only for Windows. I didn't test on linux yet).
