opencv make 时报错 - 详解

(.text+0x65d): undefined reference to `cv::namedWindow(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, int)'

(.text+0x6d6): undefined reference to `cv::imshow(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&, cv::_InputArray const&)'

(.text+0x70d): undefined reference to `cv::waitKey(int)'

需要在CMakeLists.txt中配置：

find_package(OpenCV REQUIRED)

link_libraries(

${OpenCV_LIBS}

)
