如何将OpenCV 4与ROS一起使用？

我正在尝试在windows上使用OpenCV 4.2.0运行ROS Melodic我的CmakeList有什么问题？我已将OpenCV添加到我的系统路径，但Catkin_make始终会出现以下错误：

Could not find a configuration file for package "OpenCV" that is compatible
  with requested version "4.2.0".
  The following configuration files were considered but not accepted:
    C:/opt/rosdeps/x64/CMake/OpenCVConfig.cmake, version: 3.4.1

它找到的版本是ROS melodic发行版附带的OpenCV。如何更改CMake搜索的位置

这是我的名片：

试着告诉CMake你的OpenCV在哪里，也许它会寻找第一个，如果找到可以使用的力

find_package(OpenCV REQUIRED PATHS Path/to/OpenCV NO_DEFAULT_PATH)

这半部分工作正常-现在它找到了包的名称，但是我得到了一个错误：错误C2039:“warpPolar”：不是“cv”的成员。。。它正在rosdeps中查看ros附带的opencv 3.4.1版本。您确定可以使用cv_bride使用“外部”opencv吗？我不确定是否可能，请检查一下
