不同的项目可能需要装不同版本的opencv，已经在/usr/local里装好了opencv3.4.1，下次需要装其他版本的要记得不要make install，而且要在cmakelists.txt里标记好cv_bridge的文件位置。如：
set(OpenCV_DIR “/home/nvidia/opencv/opencv-3.4.1/build”)
set(cv_bridge_DIR /usr/local/share/cv_bridge/cmake)

ros(13):ros找不到包报错及解决办法–Config.cmake
3.1q

3一文搞清楚cmake 是怎么找到包的位:3.2
ERROR报错:

Errors     << vins:check /home/nvidia/catkin_ws/logs/vins/build.check.005.log        
CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:85 (find_package):
  Could not find a package configuration file provided by "cv_bridge" with
  any of the following names:

    cv_bridgeConfig.cmake
    cv_bridge-config.cmake

  Add the installation prefix of "cv_bridge" to CMAKE_PREFIX_PATH or set
  "cv_bridge_DIR" to a directory containing one of the above files.  If
  "cv_bridge" provides a separate development package or SDK, be sure it has
  been installed.

编译完cv_bridge源码之后，命令行显示cmake地址：

cmake文件下的几个文档是用来给其他cmake项目调用的，如下chat解释的那样

在catkin_ws中进行编译时候，用到cv-bridge时候，需要在cmakelist中调用本地编译的cvvridge

include(/home/nvidia/opencv-gpu/opencv-3.4.1/build/OpenCVConfig.cmake)

set(cv_bridge_DIR /usr/local/share/cv_bridge/cmake) #没有这句话下面找不到包会报错
find_package(catkin REQUIRED COMPONENTS
    roscpp
    std_msgs
    geometry_msgs
    nav_msgs
    tf
    cv_bridge#此处会报错
    camera_models
    image_transport)

  Could not find a configuration file for package "OpenCV" that is compatible
  with requested version "4".

解决方法：

修改Fast-Drone-250-master/src/realflight_modules/VINS-Fusion/camera_models/CMakeLists.txt文件

将find_package(OpenCV 4 REQUIRED)改为find_package(OpenCV 3 REQUIRED)
