Redownload Option

FFmpegKit repository does not include the source code of any external library including FFmpeg. The source code of external libraries is automatically downloaded by the top level build scripts at the beginning of the build process.

If their source code is already downloaded and extracted, then the build scripts will not download them again to complete the compilation faster. However, if you need to re-download their sources, you can use --download-LIBRARY option. This option will download the source code even if it is found locally.
