title: I cannot install ffmpeg-light on Windows 10
body: <p>I'm trying to install ffmpeg-light with Stack, but pkg-config was not found. I'been searching for people with the same problem but none of the answers seemed to fix my problem. This is the output I get whenever I try to install. If someone could help, I would be really happy.</p>
