Hi,

I compiled Paraview using the following configuration in a cmake file. After a successful compilation, I got the following error:

`Got unknown argument: --egl-device-index=0. Could you have misspelled your Python file path or name?`

Here is the configuration of my Paraview build put in a cmake file:

PS: I was trying to build Paraview in offscreen rendering mode with EGL on headless nodes to use the cluster variant of Nvidia IndeX
