Questions about bulild #6

Thanks for creating this great resource. I have a question regarding build: the following error is displayed

CMake Error at /home/wang/ws_fast_lio_sam/src/FAST-LIO-SAM/fast_lio_sam/CMakeLists.txt:60 (add_executable): Target "fast_lio_sam_node" links to target "Boost::timer" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?

CMake Error at /home/wang/ws_fast_lio_sam/src/FAST-LIO-SAM/fast_lio_sam/CMakeLists.txt:55 (add_library): Target "fast_lio_sam_methods" links to target "Boost::timer" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?

CMake Error at /home/wang/ws_fast_lio_sam/src/FAST-LIO-SAM/fast_lio_sam/CMakeLists.txt:53 (add_library): Target "fast_lio_sam_constructor" links to target "Boost::timer" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?

CMake Error at /home/wang/ws_fast_lio_sam/src/FAST-LIO-SAM/fast_lio_sam/CMakeLists.txt:57 (add_library): Target "fast_lio_sam_callbacks" links to target "Boost::timer" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing?

How can I solve these problems？

Sorry for the late and glad to see that you solved the problem from your end :)

很抱歉迟到了，很高兴看到您从最终解决了问题:)

Thank you for opening the algorithm. I would like to ask you, what do the two rviz interfaces open at the same time mean respectively

Hi @wangchuanhao1231 The one is representing the result from FAST-LIO and the another one is representing the result from FAST-LIO-SAM, which includes loop-closing and Pose Graph Optimization to correct the drift.

嗨，一个代表 FAST-LIO 的结果，另一个代表 FAST-LIO-SAM 的结果，其中包括闭环和姿态图优化来纠正漂移。
