Installing libusb on windows for use with Qt - c++

Question

I'm trying to install libusb (not libusb-win32) on windows 7. I have to link it with Qt 5.0.1. Here are the problems I'm facing
In the INSTALL file in the extracted libusb folder, it tells me to cd to the current folder then run
./configure
make
makeinstall
But I got the error
'./configure' is not recognized as a valid command.
Googling this problem usually gives the solution as installing libusb-win32. However, I want to avoid that, as of now.
In the libusb library, there were a few MSVC projects, so I built them. That did generated some .lib files. So I proceeded to link them with my Qt project. It recognizes the libusb.h header file but does not link properly. Here is my .pro file
QT += core gui widgets
TARGET = Qt_libusb TEMPLATE = app
SOURCES += main.cpp\
qt_libusb.cpp
HEADERS += qt_libusb.h
FORMS += qt_libusb.ui
LIBS += -LC:\libusb-1.0.18\Win32\Debug\lib\libusb-1.0
INCLUDEPATH += C:/libusb-1.0.18/libusb DEPENDPATH += C:/libusb-1.0.18/libusb
My objective is to link the libusb library with Qt. Please tell me if I haven't 'installed' the library correctly or if I am linking it in a wrong way. thanks

Answer 1

Your project file does not reference the library. You only provide a path where libraries might be found, but there's no reference to the libusb library itself.
What you're missing is something like
LIBS += -llibusb
You also can't have multiple project file statements on the same line. The below is an error:
TARGET = Qt_libusb TEMPLATE = app
It should look like:
TARGET = Qt_libusb
TEMPLATE = app
