[Cin] zscale plugin

I wanted to try the "zscale" plugin of ffmpeg (inside CinGG, of course). I installed the zimg library and now I need to configure FFmpeg with --enable-libzimg. How can I do this? https://ffmpeg.org/ffmpeg-filters.html#zscale-1 https://github.com/FFmpeg/FFmpeg/commit/416e35e5aafc2a2bf77372d5e8479c28796d...
