编译安装opencv3.4 rebuild the library with windows gtk+ 2.x

在执行imshow函数时，出现如下error
OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with Windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvShowImage, file /home/nvidia/Documents/opencv-3.4.0/modules/highgui/src/window.cpp, line 611 terminate called after throwing an instance of cv::Exception
解决方法：

除了提前安装 install libgtk2.0-dev and pkg-config 这两个包还在 还需要

在cmake时加入-D WITH_QT=ON 选项

WITH_GTK = ON 

WITH_GTK_2_X =ON

重新编译安装即可
