Since Resolve (and the free Resolve Lite) doesn't support one OpenFX method,
the Openfx-Misc set of free plugins needed an update.
After a discussion in the Blackmagic forum, this has now happened.
I was able to compile them without any issues and they do show up in my Resolve 11 Lite on MacOS.
a side node: openfx_yadif (for deinterlacing) is still crashing in export after 5-20
frames. It does work in the color tab. Even with playback running.
