problem about "libnano" while compiling and methods to solve

[BIT-TYJ]

Hello, someting goes wrong when I compile DiSCo-SLAM, in the following:
(1)Target "lio_sam_mapFusion" links to target "libnabo::nabo" but the target
was not found.

SOLVE:
I change:
# Map Fushion libnabo::nabo
add_executable(${PROJECT_NAME}_mapFusion src/DiSCo-SLAM/mapFusion.cpp)
add_dependencies(${PROJECT_NAME}_mapFusion ${catkin_EXPORTED_TARGETS} ${PROJECT_NAME}_generate_messages_cpp)
target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} libnabo::nabo}
to
# Map Fushion libnabo::nabo
add_executable(${PROJECT_NAME}_mapFusion src/DiSCo-SLAM/mapFusion.cpp)
add_dependencies(${PROJECT_NAME}_mapFusion ${catkin_EXPORTED_TARGETS} ${PROJECT_NAME}_generate_messages_cpp)
target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} nabo}
(2) the second problem is:
/usr/bin/ld: //usr/local/lib/libnabo.a(kdtree_cpu.cpp.o): undefined reference to symbol 'GOMP_parallel@@GOMP_4.0'
//usr/lib/x86_64-linux-gnu/libgomp.so.1: 无法添加符号: DSO missing from command line

SOLVE:
I change:
# Map Fushion libnabo::nabo
add_executable(${PROJECT_NAME}_mapFusion src/DiSCo-SLAM/mapFusion.cpp)
add_dependencies(${PROJECT_NAME}_mapFusion ${catkin_EXPORTED_TARGETS} ${PROJECT_NAME}_generate_messages_cpp)
target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} nabo}
to
# Map Fushion libnabo::nabo
add_executable(${PROJECT_NAME}_mapFusion src/DiSCo-SLAM/mapFusion.cpp)
add_dependencies(${PROJECT_NAME}_mapFusion ${catkin_EXPORTED_TARGETS} ${PROJECT_NAME}_generate_messages_cpp)
target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} nabo
gtsam fast_max-clique_finder scan_context "/usr/local/lib/libnabo.a" "/usr/lib/x86_64-linux-gnu/libgomp.so.1")

Then the compilation succeeded.

I change

target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} libnabo::nabo}

to

target_link_libraries(${PROJECT_NAME}_mapFusion ${catkin_LIBRARIES}
${PCL_LIBRARIES} ${libnabo_LIBRARIES}
gtsam fast_max-clique_finder scan_context)

[haonimaqaq]

change
${PCL_LIBRARIES} libnabo::nabo}
to
${PCL_LIBRARIES} nabo
add
gtsam fast_max-clique_finder scan_context "/usr/local/lib/libnabo.a" "/usr/lib/x86_64-linux-gnu/libgomp.so.1")
