CMake build for QExtSerialPort for all those lonely cross-platform Qt4 projects

rect6492So QSerialPort only became part of Qt core on Qt5.1, but what should all those Qt4 projects do for an easy serial port access?
There is the excellent QExtSerialPort project, but it only has a QMake build system, and I like CMake!
Not to worry, a CMake build is easy to set up…
