The compiler can not find a description of these two externals: imgshow(), cv::CascadeClassifier::CascadeClassifier()

I connected all the lib files that I had, here's the list: opencv_face400d.lib, opencv_calib3d400d.lib, opencv_core400d.lib, opencv_features2d400d.lib, opencv_flann400d.lib, opencv_highgui400d.lib, opencv_imgcodecs400d.lib, opencv_imgproc400d.lib, opencv_ml400d.lib, opencv_objdetect400d.lib, opencv_photo400d.lib, opencv_datasets400d.lib, opencv_shape400d.lib, opencv_stitching400d.lib, opencv_superres400d.lib, opencv_video400d.lib, opencv_videoio400d.lib, opencv_videostab400d.lib, opencv_tracking400d.lib, opencv_img_hash400d.lib, opencv_line_descriptor400d.lib, opencv_aruco400d.lib, opencv_bgsegm400d.lib, opencv_bioinspired400d.lib, opencv_ccalib400d.lib, opencv_dnn_objdetect400d.lib, opencv_dnn400d.lib, opencv_dpm400d.lib, opencv_fuzzy400d.lib, opencv_hfs400d.lib, opencv_optflow400d.lib, opencv_phase_unwrapping400d.lib, opencv_plot400d.lib, opencv_reg400d.lib, opencv_rgbd400d.lib, opencv_saliency400d.lib, opencv_stereo400d.lib, opencv_structured_light400d.lib, opencv_surface_matching400d.lib, opencv_text400d.lib, opencv_xfeatures2d400d.lib, opencv_ximgproc400d.lib, opencv_xobjdetect400d.lib, opencv_xphoto400d.lib

Does anyone know what lib files need to be connected so that these functions start working?

Does anyone know what lib files need to be connected so that these functions start working?there are error messages which I got:
