Add new SLAM to LidarView superbuild as independent plugin
Deprecates old LidarView SLAM implemented by LidarPlugin, and replaces it by independent LidarSlamPlugin.
If SLAM is enabled, LidarSlamPlugin is automatically built and installed as a Lidarview plugin, and will be auto-loaded at LidarView start. Its use is then totally transparent for the user.
Major changes :
- Add LiDAR SLAM submodule
- Upgrade Eigen from 3.2.10 to 3.3.7 : Eigen 3.3 needed by new SLAM.
- Upgrade PCL from 1.8.1 to 1.10.1 : the upgrade to Eigen 3.3 revealed a major drawback when using the same Eigen files but compiled in different libs with different optimizations flags turned on. The upgrade to PCL >1.9 fixes a CMake bug in PCL exporting wrong optimization flags, leading to weird dynamic Eigen matrices alignement errors. See this commit for more info.
- Various CMake modifications
