collect2: error: ld returned 1 exit status
imu_gps_localization/CMakeFiles/imu_gps_localization_node.dir/build.make:117: recipe for target '/home/liu/demo2/devel/lib/imu_gps_localization/imu_gps_localization_node' failed
make[2]: *** [/home/liu/demo2/devel/lib/imu_gps_localization/imu_gps_localization_node] Error 1

解决办法：

在cmake.list中的target_link_libraries()中添加gflags即可。
