Setting import from window to webpack?

Question

webpack

The site connects the Modernizr library directly through the script tag, below it connects a bundle assembled from many files and libs. I use webpack to build.
Problem when accessing the Modernizr library.
Is it possible to somehow make it clear to webpack that this variable (Modernizr) is taken directly from window.
I am compiling the webpack from scratch, because the contractors handed over the sources but not the build scripts, and now I need to tweak the scripts.
