You should provide more information: how did you add poppler lib to your project? Can you show your PRO file?

One thing that I notice is I believe you have to add 'mobility' to CONFIG

CONFIG += c++11 mobility

EDIT: Well, reading the documentation further, that may not be the case in your situation.

Do you try to build for Android?

android: {
    INCLUDEPATH += /usr/local/include/poppler/qt5
    LIBS += -L/usr/local/lib -lpoppler-qt5
}

If so then you need poppler lib built for Android.
