On Dev Build: "Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated."

[CNLohr]

I'm building OBS from source on Linux Mint Mate 20 with the following cmake command (as I had difficulty getting all of the prereq's working)

cmake .. -DENABLE_PIPEWIRE=OFF -DBUILD_BROWSER=OFF -DBUILD_VST=OFF

It builds fine, but when I run I get the error below. Note that I am now running nvidia-495 (the brand newest drivers, I tried with 460 as well). I can verify that glxinfo works properly. Any idea why I can't start OBS?
