windows使用mingw+cmake编译二维码生成库libqrencode

libqrencode介绍

Libqrencode is a fast and compact library for encoding data in a QR Code symbol, a 2D symbology that can be scanned by handy terminals such as a mobile phone with CCD. The capacity of QR Code is up to 7000 digits or 4000 characters and has high robustness.
Libqrencode accepts a string or a list of data chunks then encodes in a QR Code symbol as a bitmap array. While other QR Code applications generate an image file, using libqrencode allows applications to render QR Code symbols from raw bitmap data directly. This library also contains a command-line utility outputs QR Code images in various formats.

看到网上是使用vs编译libqrencode，我看到源码目录有CMakeLists.txt，说明可以使用cmake工具进行编译。于是使用cmake+mingw编译libqrencode
