[opensuse-factory] New package: zxing-cpp - C++ library for barcode extraction

Hello, I've just filed https://build.opensuse.org/request/show/704388 to request inclusion of the "zxing-cpp" library in Tumbleweed. zxing-cpp is a C++ port of the ZXing ("zebra crossing") Java library for 1D and 2D barcode detection and extraction, which was used in the Android application "Barcode Scanner". ZXing by itself is in maintenance mode, but zxing-cpp is an officially sanctioned fork of the original C++ port[1], is maintained, and has regular releases. This library, upon acceptance, will be used by the "kitinerary" package (part of KDE Applications) to process barcodes shown in reservation tickets[2].
