在编译一个使用OpenCV的开源项目时，CMakeLists配置出错。错误源于未正确设置OpenCV的路径。通过修改CMakeLists，尝试使用find_package()并设置OpenCV_DIR，但仍然遇到找不到库和头文件的问题。最终，通过添加头文件路径和库路径解决了部分问题，但仍有找不到opencv.lib的错误。问题在于未指定正确的库文件名。寻求进一步的解决方案。

问题

编译一个开源项目，该项目的Cmakelist：

find_package(OpenCV QUIET COMPONENTS core highgui imgproc imgcodecs)
if(NOT OpenCV_FOUND)
    find_package(OpenCV REQUIRED COMPONENTS core highgui imgproc)
endif()

cmake后出错：

CMake Error at examples/CMakeLists.txt:5 (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" 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,
