Build errors that occur with srrg2_slam_interfaces

[Kana-Na]

Hello.

Thanks for sharing this slam. I want to run this slam and have set up a build environment. However, I get an error in srrg2_slam_interfaces and cannot build it. I am using Ubuntu 18.04 and ROS is melodic. Could you please tell me how to solve this problem? This problem is the same as the following two

・build error with srrg2_slam_interfaces · Issue #4 · srrg-sapienza/srrg2_proslam (github.com)

・Build error and Localization mode · Issue #2 · srrg-sapienza/srrg2_slam_interfaces (github.com)
