/home/jyyang/catkin_ws/src/ORB-SLAM2_with_line-master/Examples/ROS/ORB_SLAM2/../../../include/System.h:29:10: fatal error: pcl/common/common_headers.h: 没有那个文件或目录
 #include

解决办法，cmakelist下没有链接pcl库，在cmakelist下加入

find_package(PCL 1.9.1 REQUIRED )  #添加了稠密点云显示，用到了pcl库，要找到PCL库并添加进来

include_directories(
${PROJECT_SOURCE_DIR}
${PCL_INCLUDE_DIRS}
${PROJECT_SOURCE_DIR}/../../../
${PROJECT_SOURCE_DIR}/../../../include
${Pangolin_INCLUDE_DIRS}
)

link_directories( ${PCL_LIBRARY_DIRS} )

set(LIBS 
${OpenCV_LIBS} 
${EIGEN3_LIBS}
${Pangolin_LIBRARIES}
${PROJECT_SOURCE_DIR}/../../../Thirdparty/DBoW2/lib/libDBoW2.so
