 Hi. Have some trouble building ffmpeg with decklink option.
 Seems to be related to cc5844 ffmpeg commit
 (https://github.com/FFmpeg/FFmpeg/commit/cc5844da988fb7ca1051775a3dac43de77bf3881)

 Using media_autobuild_suite with "enable-decklink" option active I've got
 this error message:


 {{{

 Use headers from v11.6 decklink SDK.
