OpenCV extended image processing - filters

Question

How do I access the OpenCV extended image process module? I need one filter specifically: fastGlobalSmootherFilter.

I have OpenCV 3.2.0 incorporated into my C++ project. I'm looking for this method: http://docs.opencv.org/master/da/d17/group__ximgproc__filters.html#gaf8673fe9147160ad96ac6053fac3c106

which is in this module: http://docs.opencv.org/master/df/d2d/group__ximgproc.html.

I found it through the research page here: https://sites.google.com/site/globalsmoothing/

I've tried searching through the OpenCV header files, but none reference this function. I can't find edge_filter.hpp which is supposed to house some of these filters. How does one actually call the method?

At OpenCV developer site, you will find instructions for building the contrib modules (or extras)

https://github.com/opencv/opencv_contrib/blob/master/README.md

By default, they are not included in your build.
