Is this the right way to cope with this? At least it compiles, links and works ;-)
I stumbled over a similar issue, it has also been fixed in the release/3.1 branch but after n3.1.3 in commit 12320c08221f0eecf6d9af3a6f12f42e656f0674.
See https://ffmpeg.org/pipermail/ffmpeg-devel/2016-August/198476.html
In current git I found #ifdef _WIN32 #include <windows.h> #endif, which does not work under cygwin. Apparently _WIN32 is not defined in this environment.
But in this case SetDllDirectory() is not called as it's also ifdef-depending on _WIN32.
