WIP: Update LidarView superbuild with this Lidar SLAM
Replace old LidarView SLAM by this repo.
This MR introduces new features necessary for integration to LidarView Superbuild:
- clean installation of lib and header files
- CMake stuff updates and default settings
- PUBLIC/PRIVATE dependencies management
- set G2O dependency as optional and compile pose graph optimization stuff only if G2O is available
- small fixes to remove compilation warnings for cleaner build
