cmakelist opencv

在CMakeList文件中使用find_package命令来查找OpenCV库时，需要根据不同的情况进行配置。如果需要使用opencv3，可以在CMakeList文件中添加以下配置内容：\[1\]

set(OpenCV_DIR /usr/local/share/OpenCV) # 设置opencv3的OpenCVConfig.cmake文件
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_include_Path: " ${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_Library_Path: " ${Opencv_LIBRARIES})

如果需要使用ROS自带的OpenCV库，可以使用以下配置内容：\[2\]

set(OpenCV_DIR /usr/share/OpenCV) # 设置ROS自带的OpenCV路径
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_include_Path: " ${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_Library_Path: " ${Opencv_LIBRARIES})

另外，在Ubuntu系统中可能会同时安装opencv3和opencv4的版本。如果需要使用opencv4，可以在CMakeList文件中添加以下配置内容：\[3\]

set(OpenCV_DIR /usr/lib/cmake/opencv4) # 设置opencv4的OpenCVConfig.cmake文件
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_include_Path: " ${OpenCV_INCLUDE_DIRS})
message(STATUS "Opencv_Library_Path: " ${Opencv_LIBRARIES})

以上配置内容可以根据实际情况进行调整，确保CMake能够正确找到并链接OpenCV库。
