Build error and Localization mode

[jojo89776]

First, thank you for sharing your great work!

1. When I tried to build and execute the code following the instruction(https://github.com/srrg-sapienza/srrg2_slam_interfaces/blob/master/srrg2_slam_interfaces/README.md), I met some errors as follows.
   There was no error on building srrg2_core (https://github.com/srrg-sapienza/srrg2_core/tree/master/srrg2_core).
   Do you have any idea of fixing the following errors?

2. Does this project support or provide a localization-only mode for navigation??

I appreciate any comments! Thank you!.
