Description
The last couple of months I've successfully cross-compiled several static FFmpeg builds. Now I've been trying to cross-compile a shared FFmpeg build with this script, but it constantly errors out at 'avfilter-6.dll':

What am I doing wrong? Am I missing something? Is this a linker-issue of some sort?
