Using other SLAM

[dubing-bit]

I tried to use deep learning feature detection method to replace ORB,based on ORB-SLAM3 the modification was done and is tested feasible. I tried to compile OpenREALM using the modified ORB-SLAM3. the compilation process was smooth, including Openrealm and OpenREALM_ROS1_Bridge. unfortunately, no results were produced at the end. I think it's the SLAM used in Openrealm that is replaceable, but from compilation experience, it's usually easier to compile successfully using your RepositoriesSLAM libraries (including ORB-SLAM3 https://github.com/laxnpander/ORB_SLAM3 and OpenVSLAM https://github.com/laxnpander/openvslam ). Is there anything I should be concerned of when using other SLAM libraries?
