    Default Using libusb with QT Creator in Windows

    Ok, so I'm having some problems linking the library into my project for QT creator Windows.

    Here is the contents of my .pro file:

    #-------------------------------------------------
    #
    # Project created by QtCreator 2014-08-04T09:44:21
    #
    #-------------------------------------------------

    QT += core gui
    greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

    TARGET = usb_hid_api
    TEMPLATE = app


    SOURCES += main.cpp\
    mainwindow.cpp

    HEADERS += mainwindow.h\

    FORMS += mainwindow.ui

    CONFIG += console

    unix|win32: LIBS += -L$$PWD/../libusb_win/MinGW64/static/ -lusb-1.0

    INCLUDEPATH += $$PWD/../libusb_win/include/libusbx-1.0
    DEPENDPATH += $$PWD/../libusb_win/include/libusbx-1.0


    I get as a result of my problems:
    undefined reference to 'libusb_error_name@4' line 16
    undefined reference to 'libusb_init@4' line 32
    etc...
    (basically a bunch of undefined references).

    Can someone tell me where I'm going wrong?

    The library is not where you think it is or the static library is not called libusb-1.0.a.
