Hi
I am using QSerialPort library in my project. I have no problem when building DYNAMIC. But, while it is building STATIC, it gives this error: "Project ERROR: Unknown module(s) in QT: serialport".

my Qt version is: Qt5.5.1

I did these works too:
1- adding #include <QSerialPort> and #include <QSerialPortInfo> to my Class
2- adding QT += core gui serialport into .pro file

Please help me to build my project Statically.
