Build error eigen Plugins

[adricort]

I am trying to build rtabmap and rtabmap_ros from source (rolling, I know binaries are not passing) as indicated in the instructions, but 2 things happen:

1. I get the following error:

Starting >>> grid_map_ros
--- stderr: rtabmap
CMake Deprecation Warning at examples/LidarMapping/CMakeLists.txt:1 (cmake_minimum_required):
Compatibility with CMake < 2.8.12 will be removed from a future version of
CMake.

Update the VERSION argument value or use a ... suffix to tell

CMake that the project does not need compatibility with older versions.

Failed <<< rtabmap [6.81s, exited with code 2]

Is there any modification in the package for it to find the eigen plugins properly? I haven't found so much documentation about it, only here, but I think it is another problem.
2. (maybe not important at the moment) libpointmatcher can't be resolved for the dependencies for jammy, is it required?

The error seems coming from grid_map_core. You can disable that dependency with cmake -DWITH_GRIDMAP=OFF ... Thanks for the link, if I can reproduce it I could give a try. What is your machine? Ubuntu 22.04 with ROS2 Humble? From CI, rtabmap should build on jammy/humble even with ros-humble-grid-map-core dependency, see log here: https://github.com/introlab/rtabmap/actions/runs/9238128356/job/25415869022

libpointmatcher from ros-humble-libpointmatcher should also work.
