CMake Changes

This is the changes made by Patrick Plenefisch converting the native
code to use CMake and the CMake Maven Plugin, as opposed to the
native Maven plugin. This is to allow for compatibility with newer
versions of the GCC toolchain. All the cpp sources were moved from
maven style directories to cpp style directories for CMake.
