[vtkusers] Problem with webpack configuration on CentOS

[Andrzej Marciniak]

Hi,

We have application with VTK viewer working properly on Windows, MacOS and
Ubuntu, but when I migrated it to CentOS 7.3, the viewer does not work. When
shaders are compiled, the code of Shader is prefixed with:
"module.exports = ",
eg. 
"module.exports = "#version 300 es↵#define attribute ...etc. etc.

What can be wrong?
We use the following dependencies:
