I encountered this problem when compiling:
"In file included from /ws_livox/src/G3Reg-main/Thirdparty/robot_utils/include/nanoflann/KDTreeVectorOfVectorsAdaptor.h:31:0,

compilation terminated.
CMakeFiles/g3reg.dir/build.make:89: recipe for target 'CMakeFiles/g3reg.dir/src/back_end/pagor/geo_verify.cpp.o' failed

I think there is something wrong with the header file reference of this file: "G3Reg\Thirdparty\robot_utils\src\file_manager.cpp"
