Answer 1

Okay, I think I know what happened. I tried running the program and it worked perfectly.

You have probably not linked the required DLL's.. Make sure (in case you are using Windows) your opencv/bin is included in your environment variables. This is my CMakeLists.txt file to make things easier for you,

cmake_minimum_required(VERSION 2.6 FATAL_ERROR)
project(SO_example)

FIND_PACKAGE(OpenCV REQUIRED)

SET (SOURCES
    #VTKtoPCL.h
    main.cpp
    )

add_executable(so_example ${SOURCES})
target_link_libraries(so_example ${OpenCV_LIBS})

Answer 2

It seems like VideoCapture can't grab frame from your camera. Add this code to check result of frame grabbing:

//create a loop to capture and find faces
while (true)
{
    //capture a new image frame
    captureDevice >> captureFrame;
    if (captureFrame.empty())
    {
        cout << "Failed to grab frame" << endl;
        break;
    }
    ...

If it is a problem of VideoCapture check that you installed drivers for your camera.
