Using cuda with Qt Creator in Windows

Does anyone know if it is possible to use cuda within Qt Creator in Windows? I am looking for step by step instructions or a video tutorial on how to do this.

I have written an application in Qt and c++ which removes moving objects from images or video but it can take 30 mins to process if the images are large.

It is perfect for cuda acceleration but I don’t know how to get cuda inside Qt.

I can write cuda inside visual studio but it’s no use if I can’t use it as an integrated part of my program.

I have been searching for the answer to this for weeks but not found anything which adequately does this.

This is what I have so far inside the pro file.

QT += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

CONFIG += c++11

The following define makes your compiler emit warnings if you use

any Qt feature that has been marked deprecated (the exact warnings

depend on your compiler). Please consult the documentation of the

deprecated API in order to know how to port your code away from it.


You can also make your code fail to compile if it uses deprecated APIs.

In order to do so, uncomment the following line.

You can also select to disable deprecated APIs only up to a certain version of Qt.

#DEFINES += QT_DISABLE_DEPRECATED_BEFORE=0x060000 # disables all the APIs deprecated before Qt 6.0.0




Default rules for deployment.

qnx: target.path = /tmp/$${TARGET}/bin
else: unix:!android: target.path = /opt/$${TARGET}/bin
!isEmpty(target.path): INSTALLS += target

win32: LIBS += -L$$PWD/’…/…/…/…/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.2/lib/x64/’ -lcuda

INCLUDEPATH += $$PWD/’…/…/…/…/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.2/lib’
DEPENDPATH += $$PWD/’…/…/…/…/Program Files/NVIDIA GPU Computing Toolkit/CUDA/v9.2/lib’
