autoware解决报错：get_Depth.cpp:(.text+0x9c8): undefined reference to `cv::Mat::Mat()‘_autoware编译 data_preprocessor报错

遇到报错：

解决方法：

找到data_preprocessor功能包的的Cmakelist.txt文件，进行如下修改：

//指定OpenCV，此处为你安装的版本
find_package(OpenCV 3.4 REQUIRED)

include_directories(
  ${catkin_INCLUDE_DIRS}
  ${OpenCV_INCLUDE_DIRS}
)

target_link_libraries(get_Depth ${catkin_LIBRARIES} ${OpenCV_LIBS})
target_link_libraries(get_PCD ${catkin_LIBRARIES} ${OpenCV_LIBS})
target_link_libraries(get_Image ${catkin_LIBRARIES} ${OpenCV_LIBS})
