OBS-Studio installation fails

[ra9hur]

Tried installing OBS-Studio to enable nvenc on ubuntu 16.04 using build script provided here. After installation, obs-studio nvenc encoder lists in the drop-down, but fails when I start recording.

Now, I am unable to uninstall obs-studio. Tried below options.

1. Not able to see this in Ubuntu software list.
2. This does not get identified with "sudo apt-get remove --purge OBS*"
3. Tried sudo make uninstall - says uninstall script is not available.

However, when I search for OBS-Studio, it shows up and I am able to open the application as well.

Please help with the uninstallation steps.
