Trying to install onevpl-cpu on 32-bit Slackware, of course
svt-hevc fails and linking fails too ...
I wonder if it buildable in 64-bit environments?
https://github.com/oneapi-src/oneVPL-cpu/blob/master/INSTALL.md
so, after installing in /usr/local it need this
guest@slax:/dev/shm/libvpl-2022.2.5/build$ source
/usr/local/etc/vpl/vars.sh
basically add environment variables ...
now vpl-inspect, system_analyzer and sample_decode works!
