zxing_cpp_no_cmake

https://github.com/glassechidna/zxing_cpp.rb

A barcode and QR code library that works with regular Ruby (not just JRuby). This gem comes bundled with ZXing C++ (zxing-cpp) and interfaces with it using FFI. As such this gem works with most major Ruby distributions. Modified to not require CMake as a build dependency.
