当使用CMake进行C/C++项目编译，结合OpenCV库时，可能会遇到找不到OpenCVConfig.cmake的问题。解决方法是通过`locate`命令找到OpenCVConfig.cmake的路径，然后在CMakeLists.txt中设置`OpenCV_DIR`为正确路径，例如 `/usr/local/opencv/4.5.1/lib/cmake/opencv4/`。这样可以确保CMake正确找到OpenCV的配置文件并完成编译。

问题1: cmake 进行 c/c++ 联合opencv编译时出现

Could not find a package configuration file provided by "OpenCV" with any
of the following names:

OpenCVConfig.cmake
opencv-config.cmake

原始CMakeLists.txt

cmake_minimum_required(VERSION 3.0	FATAL_ERROR)

project(trans)
find_package(OpenCV REQUIRED)

# Print some message showing some of them

message(STATUS "OpenCV library status:")
message(STATUS "    config: ${OpenCV_DIR}")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

add_executable(Transform Transform.cpp)
target_link_libraries(Transform "${OpenCV_LIBS}")

解决方案:

# locate 全局搜索一下该文件，没有locate可以 apt install locate
>>  locate OpenCVConfig.cmake

搜索结果会出现很多，选择安装路径下对应的OpenCVConfig.cmake 即可。
本文安装了两个版本，选择自己对应的即可。


/usr/local/opencv/3.4.9/share/OpenCV/OpenCVConfig.cmake
/usr/local/opencv/4.5.1/lib/cmake/opencv4/OpenCVConfig.cmake


opencv3 和 opencv4 的OpenCVConfig.cmake位置不一样，请确定自己版本对症用药。

在CMakeLists.txt中用

set(OpenCV_DIR /usr/local/opencv/4.5.1/lib/cmake/opencv4/)

指定对应的OpenCVConfig.cmake路径即可。

cmake_minimum_required(VERSION 3.0	FATAL_ERROR)

project(trans)
# 指定opencv 对应的OpenCVConfig.cmake 文件目录。 opencv4 不在share目录下。
# 可以用locate OpenCVConfig.cmake 全局搜索下该文件
set(OpenCV_DIR /usr/local/opencv/4.5.1/lib/cmake/opencv4/)
# 这里的OpenCV 会对应查找 OpenCVConfig.cmake 文件
find_package(OpenCV REQUIRED)

# Print some message showing some of them

message(STATUS "OpenCV library status:")
message(STATUS "    config: ${OpenCV_DIR}")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

add_executable(Transform Transform.cpp)
# target_link_libraries(CrnnEval_batch ${OpenCV_LIBS})
target_link_libraries(Transform "${OpenCV_LIBS}")
# set_property(TARGET lltm PROPERTY CXX_STANDARD 11)
