sudo apt-get install ros-melodic-qt-create ros-melodic-qt-build

/opt/ros/melodic/share/cv_bridge/cmake/cv_bridgeConfig.cmake:113: error: Project ‘cv_bridge’ specifies ‘/usr/include/opencv’ as an include dir, which is not found. It does neither exist as an absolute directory nor in ‘${prefix}//usr/include/opencv’. Check the issue tracker ‘https://github.com/ros-perception/vision_opencv/issues’ and consider creating a ticket if the problem has not been reported yet. /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:76 (find_package) robot_hmi/CMakeLists.txt:14 (find_package)

修改方法：只需修改上述路径中的cv_bridgeconfig.cmke文件，将100行附近的两个opencv改成opencv4即可（注意，只需要改动单独一个的opencv,前面有连字符的opencv不需要改动）
