Unable to colcon build rtabmap_sync package

[sa32953]

Hi, I am trying to build from source as mentioned here in ros2 branch of the repo: https://github.com/introlab/rtabmap_ros/tree/ros2.

I am building it on Ubuntu 22.04 on a VM with ROS2 Humble as distribution. I am unable to build a specific pakcages i.e. rtabmap_sync.
When I try to build it, it completes 21% and the system freezes every time. Here's the colcon command I am running in the workspace.

colcon build --symlink-install --cmake-args -DRTABMAP_SYNC_MULTI_RGBD=ON -DRTABMAP_SYNC_USER_DATA=ON -DCMAKE_BUILD_TYPE=Release --packages-select rtabmap_sync

Any hints what could be the reason for this?

I also tried building by limiting the parallel workers using the below command. Same issue persists!

colcon build --symlink-install --cmake-args -DRTABMAP_SYNC_MULTI_RGBD=ON -DRTABMAP_SYNC_USER_DATA=ON -DCMAKE_BUILD_TYPE=Release --packages-select rtabmap_sync --parallel-workers 2
