Can't get Qt Creator to Properly Compile OpenCV - c++

Question

I am trying to compile a Qt project and it seems like OpenCV is having problems. From what I have read so far, this could likely be a compiler/linkage problem. I have tried a couple different compilers without any success. Other libraries seem to be fine (libtiff, STD, other Qt libraries), but OpenCV is causing problems. I haven't for the life of me been able to make any progress on fixing it, any suggestions would be much appreciated. Posted below are things that I believe might be valuable in finding a solution.
Qt Makefile (.pro):
QT += core gui multimedia widgets multimediawidgets opengl
TARGET = LAUWebCalTag
TEMPLATE = app
DEFINES += QT_DEPRECATED_WARNINGS
SOURCES += \
main.cpp \
laumemoryobject.cpp \

HEADERS += \
laumemoryobject.h \
lauwebcamerawidget.h \
lauvideosurface.h \
lauvideoglwidget.h \
laucaltagglwidget.h \
laucaltagglobject.h

CONFIG(release, debug|release): LIBS += -lopencv_world310
CONFIG(debug, debug|release): LIBS += -lopencv_world310d
}

Build and Run:
[Build and Run Kit Options]
[CMake (Not 100% sure if CMake is necessary for this project or right)]
I also thought the way cv:: was being declared was strange for this:
namespace cv
{
using std::vector;
}
I apologize for the dumb question, I am brand new to both Qt and OpenCV
