尝试调用静态编译的opencv
Github Project Page
Author's Notes
把Qt 4.8.1 mscv2010 运行时加入系统PATH
单击configure，共三次，第一次指定目录并选择编译器，第二次选择OpenCV配置，第三次指定qmake
output/path/install
bin/*.dll
include/*
lib/*
share/*
tidy.rb
require 'fileutils'
FileUtils.mv(Dir.glob('share/OpenCV/3rdparty/lib/*.lib'), 'lib/')
FileUtils.rm_rf('share/')
FileUtils.rm_rf('doc/')
FileUtils.rm(Dir.glob('bin/*.exe'), :force=>true)
FileUtils.rm(Dir.glob('*.cmake'), :force=>true)
FileUtils.rm(Dir.glob('*~'), :force=>true)
system("7z a static_opencv_lib.7z lib include")

HighGUI功能使用Qt支持，相关工程即使自身没有使用也需要在pro文件中加入testlib
而QT += testlib会造成多余的控制台窗口
正如这个帖子提到testlib会强制加入 CONFIG += console
testlib只在highgui中使用了一次
但该处使用涉及到按键事件循环，把Qt的按键事件转换为ASCII码，不知道有没有其他方法替代。
暂时直接去掉，看起来似乎不影响highgui的功能，另外在我的例子中cv::namedWindow没有按钮。
opencv/modules/highgui/src/windows_QT.cpp
void CvWindow::keyPressEvent(QKeyEvent *evnt)
// Qt::Key qtkey = static_cast<Qt::Key>(key);
// char asciiCode = QTest::keyToAscii(qtkey);
// if (asciiCode != 0)
// key = static_cast<int>(asciiCode);
// else
key = evnt->nativeVirtualKey(); //same codes as returned by GTK-based backend
opencv/modules/highgui/src/windows_QT.h
// #include <QtTest/QTest>
其中的MessageBoxA和GetFocus函数调用出问题，注释掉相关代码(两行)后，可以解决。
opencv/3rdparty/libtiff/tif_win32.c
static void
Win32WarningHandler(const char* module, const char* fmt, va_list ap)
//MessageBoxA(GetFocus(), szTmp, szTitle, MB_OK | MB_ICONINFORMATION);
static void
Win32ErrorHandler(const char* module, const char* fmt, va_list ap)
//MessageBoxA(GetFocus(), szTmp, szTitle, MB_OK | MB_ICONEXCLAMATION);
参见Bug #2070
Harald Schmidt给出Patch #2178。不仅解决图标显示问题，同时改进HighGUI的图标显示方式。文件分成两部分。
Patch 2304是需要修改的HighGUI代码。下载四个代码文件后，把头文件和源代码文件分别放到opencv/modules/highgui/include/opencv2/highgui和opencv/modules/highgui/src目录下。
Patch 2303是修改后，新增加功能的示例。
不好用，且留待继续测试或者新版修正
在没有必要显示像素坐标与颜色的场合，使用没有按钮的窗口。
