[Slackbuilds-users] libva required by motion

[Sebastian Arcus]

I am trying to test build the next version/generation of Motion (4.0.1 
from here: https://github.com/Motion-Project/motion/releases) to upload 
at SBo. I'm going around in circles a bit as I can't work out the 
correct requirements. The previous version has libva down as optional 
dependency, but this version doesn't seem to want to compile without it. 
I can't even find libva on SBo anyway - searching for it leads to the 
vdpau-video page - which in turn requires "a version of the proprietary 
NVIDIA display driver". I've read the various descriptions of the above 
libraries - and I can't work out:

1. if libva is really a hard dependency for motion - or how can I 
compile without it? There doesn't seem to be a corresponding switch for 
./configure
2. what is the connection between libva and vdpau-video? Is one a 
replacement for the other?
3. if vdpau-video is really required - does it literally mean I would 
have to  install NVDIA drivers on a system which doesn't even have any 
NVDIA chip?

Any clues about the above would be much appreciated. I enclose below the 
output from attempting to compile motion:
