Hello,

I saw this PR #507 by rdelfin. It can solve this issue.
open u Example/ROS/ORB-SLAM2/CMakelist.txt
and rewrite as the following :
find_package(Eigen3 3.1.0 REQUIRED)
find_package(Pangolin REQUIRED)
+find_package(Boost COMPONENTS system)

include_directories(
${PROJECT_SOURCE_DIR}
${PROJECT_SOURCE_DIR}/../../../
${PROJECT_SOURCE_DIR}/../../../include
${Pangolin_INCLUDE_DIRS}
+${Boost_INCLUDE_DIRS}
)

set(LIBS
${OpenCV_LIBS}
${EIGEN3_LIBS}
${Pangolin_LIBRARIES}
+${Boost_LIBRARIES}
${PROJECT_SOURCE_DIR}/../../../Thirdparty/DBoW2/lib/libDBoW2.so
${PROJECT_SOURCE_DIR}/../../../Thirdparty/g2o/lib/libg2o.so
${PROJECT_SOURCE_DIR}/../../../lib/libORB_SLAM2.so
