run code meet:

OpenCV Error: No OpenGL support (Library was built without OpenGL support) in cvNamedWindow, file C:\buildslave64\win64_amdocl\2_4_PackSlave-win32-vc11-shared\opencv\modules\highgui\src\window_w32.cpp, line 730

Because make Opencv without OpenGL,so i uninstall opencv under the 'build' folder,

before cmake ,we need install GTK + OpenGL Extensions,and cmake opencv with 'WITH OPENGL' choose

cd opencv-3.1/build
sudo make uninstall
cd ../ && rm -r buid
sudo apt-get install libgtkglext1 libgtkglext1-dev
cmake-gui

But when i make opencv, i meet new error:

../../lib/libopencv_cudalegacy.so.3.2.0: undefined reference to `nppiGraphcut_32s8u'
../../lib/libopencv_cudalegacy.so.3.2.0: undefined reference to `nppiGraphcutInitAlloc'
