opencv-4.5.0 版本对应的库文件 

源码编译OpenCV时，远程下载库文件有时会下载失败，可以先下载至本地，然后修改下载文件路径。
1. 修改 opencv4/opencv/3rdparty/ippicv/ippicv.cmake 43行，指定ippicv_2020_lnx_intel64_20191018_general.tgz 文件路径
2. 修改 opencv4/opencv_contrib/modules/face/CMakeLists.txt 21行，指定face_landmark_model.dat 文件路径
3. 修改 opencv4/opencv_contrib/modules/xfeatures2d/cmake/download_boostdesc.cmake 27行，制定boostdesc... 文件路径
4. 修改 opencv4/opencv_contrib/modules/xfeatures2d/cmake/download_vgg.cmake 27行，制定vgg... 文件路径
修改方式如：
```
//    ocv_download(FILENAME ${name_${id}}
//                 HASH ${hash_${id}}
//                 URL
//                   "${OPENCV_VGGDESC_URL}"
//                   "$ENV{OPENCV_VGGDESC_URL}"
//                    "file:///home/workspace/opencv_3rdparty/vgg/"        // 本地文件路径
//                    # "https://raw.githubusercontent.com/opencv/opencv_3rdparty/${OPENCV_3RDPARTY_COMMIT}/" //远程文件路径
//                 DESTINATION_DIR "${dst_dir}"
//                 ID "xfeatures2d/vgg"
//                 RELATIVE_URL
//                 STATUS res)
