解决ubuntu16.04 opencv2.4.13编译错误的过程
要在opencv中使用opengl
cmake -D CMAKE_BUILD_TYPE=Release Debug -D WITH_OPENGL=ON -D CMAKE_INSTALL_PREFIX=/usr/local .
没有添加opengl编译选项的时候是可以正常编译的，打开支持opengl编译就出现了下面的问题
开始出现的问题是找不到gtk/gtkgl.h,然后按照搜索的解决方法安装libgtkglext1-dev
sudo apt-get install libgtkglext1-dev后 make报下面的错误
//usr/lib/x86_64-linux-gnu/libgio-2.0.so.0: undefined reference to `g_option_group_unref'
//usr/lib/x86_64-linux-gnu/libgio-2.0.so.0: undefined reference to `g_thread_pool_move_to_front'//usr/lib/x86_64-linux-gnu/libgio-2.0.so.0: undefined reference to `g_sequence_is_empty'

libgio找不到libglib，但是ldd /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0是可以看到libglib路径的
/opencv2/opencv-2.4.13$ ldd /usr/lib/x86_64-linux-gnu/libgio-2.0.so.0.4800.1

不能单独配置使用opengl
使用下面的
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_TIFF=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_GTK=ON -D WITH_OPENGL=ON ..
