1. 安装CMake3.3.0，安装时选择“Add Cmake to the system PATH for all users”

2. source code 选择opencv解压路径下的sources

3. 点击Configure，界面变红后，再次点击Configure，变白后再点击Generate，那么便生成了opencv项目

4. 打开opencv.sln，点击编译。生成.dll和lib文件

5. 打开demo项目的属性管理器，demo中只修改debug下。

6. VC++目录下的包含目录不用变，库目录改为opencv项目下lib\debug，链接器->输入 下的附加依赖性不用变

demo中测试单步进入imread源码

    if( decoder.empty() )
        return 0;
    decoder->setSource(filename);
    if( !decoder->readHeader() )
        return 0;

    CvSize size;
    size.width = decoder->width();
    size.height = decoder->height();

    int type = decoder->type();
    if( flags != -1 )
    {
        if( (flags & CV_LOAD_IMAGE_ANYDEPTH) == 0 )
            type = CV_MAKETYPE(CV_8U, CV_MAT_CN(type));

        if( (flags & CV_LOAD_IMAGE_COLOR) != 0 ||
           ((flags & CV_LOAD_IMAGE_ANYCOLOR) != 0 && CV_MAT_CN(type) > 1) )
            type = CV_MAKETYPE(CV_MAT_DEPTH(type), 3);
        else
            type = CV_MAKETYPE(CV_MAT_DEPTH(type), 1);
    }

    {
        if( hdrtype == LOAD_CVMAT )

            temp = cvarrToMat(matrix);
        }
        else
        {

        }
    }
    else

        return 0;
    }

    return hdrtype == LOAD_CVMAT ? (void*)matrix :
        hdrtype == LOAD_IMAGE ? (void*)image : (void*)mat;
}
