Linker error while compiling project containing QtSerialPort (g++, kubuntu)

Question

I am trying to compile a project that uses QtSerialPort and I get a link error

g++ -m64 -Wl,-O1 -o eTerm main.o eterm.o tcpclient.o tcpserver.o udpserver.o serialserver.o qrc_eterm.o moc_eterm.o moc_tcpclient.o moc_tcpserver.o moc_udpserver.o moc_serialserver.o -L/usr/X11R6/lib64 -lQt5Widgets -L/usr/lib/x86_64-linux-gnu -lQt5SerialPort -ludev -lQt5Network -lQt5Gui -lQt5Core -lGL -lpthread /usr/bin/ld: cannot find -ludev collect2: error: ld returned 1 exit status make: *** [eTerm] Error 1

I am using QtCreator 5.2.1 under Kubuntu 14.04

udev is installed and is the last version. I only get this error when QtSerialPort is included / used, everything is fine for other projects.

#if QT_VERSION >= QT_VERSION_CHECK(5, 1, 0)
    #include <QtSerialPort/QtSerialPort>
#else
    #include <QSerialPort>
    #include <QSerialPortInfo>
#endif

The serial port is installed from libqt5serialport5-dev and libqt5serialport5 packages (I had some unsuccessful trials to install it from source at first).

Does anyone has an idea what could be causing this problem? Thanks!

Try to install package libudev-dev. For compiling you normally need a package ending on -dev which contains special compilation files. The packages without -dev are usually only for running programs which dynamically link to a library.
