This is off topic - x264 is a separate, unrelated, project.

However, the issue you have is that you have told it to build with
ffmpeg support, and not told it what extra libraries ffmpeg needs.

The whole thing - building x264 with ffmpeg support and ffmpeg with
x264 support - is sort of a chicken/egg problem. Don't do that, build
x264 without ffmpeg.
