Use of undeclared identifier in fast_clustering code

[lkorsos1]

Hey, love the ideas in this code! Was trying to run it and I've been running into the following issue when trying to run make. I'm wondering if I'm just missing something super obvious. Thanks a ton!

Ops! Can you please provide information about your operative system and architecture to reproduce the problem? Paste also the output of "cmake ."
