OpenCV4.x进行Cmake时报错"Error in configuration process,project files may be invalid"

查看错误日志，如下：

Detected processor: AMD64
sizeof(void) = 4 on 64 bit processor. Assume 32-bit compilation mode
Found PythonInterp: C:/Users/Administrator/AppData/Local/Programs/Python/Python36/python.exe (found suitable version "3.6.8", minimum required is "2.7")

上面的错误日志告诉我们出错的原因是文件“ippicv_2019_win_ia32_20180723_general.zip”下载失败。

其实不仅是文件ippicv_2019_win_ia32_20180723_general.zip缺失，另外四个文件通常也是因为无法下载而缺失。
另外四个为：

b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip
55c0bc8ad27db00116fabf06508de196-opencv_videoio_ffmpeg_64.dll
5de6044cad9398549e57bc46fc13908d-opencv_videoio_ffmpeg.dll
1d222685246896fe089f88b8858e4b2f-ippicv_2019_win_intel64_20180723_general.zip

所以缺失的五个文件如下：

b624b995ec9c439cbc2e9e6ee940d3a2-v0.1.1f.zip
55c0bc8ad27db00116fabf06508de196-opencv_videoio_ffmpeg_64.dll

在网上找了半天，找到了Cmake中的需要这五个文件，上传到CSDN上供有需要的朋友下载。因为是博主花了不少时间才找到这几个文件的，所以设置为需要花费1.9元的付费资源，敬请大家谅解。
这五个文件的下载链接如下：

使用方法如下：
解压“opencv.cache.zip”后将里面的“.cache”文件夹复制到你的OpenCV的源码目录下，如下图所示：

然后再进行Cmake。
