Building Resynthesizer for GIMP 2.10.10 on macOS - V2

Feedback is welcome and appreciated.

• If you'd prefer to do things by hand check out Version 1 of this guide.

The following documents the steps I took to compile the latest version of Resynthesizer on macOS Sierra (10.12.6) for GIMP 2.10.10.

Homebrew was used to fulfill as many dependencies as possible.
