Could NOT find FFmpeg (missing: swresample) (found version “56.1.0”)

I try to install obs (Open Broadcaster Software) in my Kali Linux 2.

I follow this instruction. I have no problem until the obs building:

cmake -DUNIX_STRUCTURE=1 -DCMAKE_INSTALL_PREFIX=/usr ..

Where I get this error:

Could NOT find FFmpeg (missing: swresample) (found version "56.1.0")

I found this topic but I can't use this command:

apt-get -t jessie-backports install libswresample-dev

Because I am on Kali Linux.

This is the output of ffmpeg command:

Use -h to get full help or, even better, run 'man ffmpeg'
