Environment Variables in Paraview

When the documentation mentions the environment variables, do they refer to the variables that you set in cmake-gui when building the paraview-superbuild?

Example, If I want to have more information for debugging purpose should I do this?

Or do they refer to the computer environment variables?

All these variable, as their name indicate, are environments variables and have noting to do with cmake.

All the variables an also define in cmake build command line
