如何修改opencv 配置在CMakeLists.txt？

[huangyhg]

一定要用opencv 3.0吗？

opencv

set(CMAKE_PREFIX_PATH ${CMAKE_PREFIX_PATH} /opt/ros/kinetic) find_package(OpenCV 3 REQUIRED) include_directories(${OpenCV_INCLUDE_DIRS}) 默认配置如上，如何在CMakeLists.txt修改opencv 配置为4.5.5？ 我装的最新版OpenCV 4.5.5, 路径在D:\OpenCV\install\opencv\build\x64\vc15，当运行CMake时，得到以下错误提示。

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required): Compatibility with CMake < 2.8.12 will be removed from a future version of CMake.

Update the VERSION argument value or use a ... suffix to tell CMake that the project does not need compatibility with older versions.

Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.19044. CMake Error at cuda_icp/CMakeLists.txt:3 (find_package): By not providing "FindOpenCV.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "OpenCV", but CMake did not find one.

Could not find a package configuration file provided by "OpenCV" (requested version 3) with any of the following names:

OpenCVConfig.cmake
opencv-config.cmake

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

Configuring incomplete, errors occurred! See also "D:/source/shape_based_matching4/CMakeFiles/CMakeOutput.log".

set(OpenCV_DIR D:/opencv/build/install) find_package(OpenCV 3 REQUIRED) include_directories(${OpenCV_INCLUDE_DIRS})

应该是需要opencv 3.0，OpenCV_DIR 想我类似那样配置，opencv 3.0最好也自己编译一下，我网上下的，在训练的时候居然不能用
