How to use openFabMap in lsd_slam

edit

I use ros-indigo and ubuntu 14.04.I ls I want to use the openFabMap in lsd_slam. I want to use the openFabMap in lsd_slam. I saw README.md.

lsd_slam_core/CMakeLists.txt :

add_subdirectory(${PROJECT_SOURCE_DIR}/thirdparty/openFabMap) include_directories(${PROJECT_SOURCE_DIR}/thirdparty/openFabMap/include) add_definitions("-DHAVE_FABMAP") set(FABMAP_LIB openFABMAP )

It was as described above.

$rosrun rqt_reconfigure rqt_reconfigure

We put a check in the useFabMap.Error came out in this way.

Warning: Compiled without FabMap, but useFabMap is enabled... ignoring.

Please tell us what to do in order to solve this problem.
