compiling on generic linux

[brothermechanic]

Hello
I never compiled plugins, but now this is no another way for me.
My linux distro is gentoo.
Ani i can't use stock install script.
I try to repeat algorithm and don't get plugin's binary
This is my log from GAME/Saved/Logs/VLC.log

Thank you in advance!

then i pack my system vlc to https://drive.google.com/file/d/1ViTocoGX5nd-6M_zAhqwjI9yRkgbC7oI/view?usp=sharing
and unpack usr to /home/bm/bin/UnrealEngine/Engine/Plugins/VlcMedia/ThirdParty/vlc/Linux/x86_64-unknown-linux-gnu/
and i get a game!
