如何在ubuntu上安装opencv_contrib？

Question

我从github https://github.com/Itseez/opencv_contrib 获得了opencv_contrib包文件 并按照README说的那样成功构建了它，

$ cmake -DOPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..

然后我输入make install来生成.so文件（我在这里误解了这个命令吗？）。 但是当我使用qt编译这个例子时，docs.opencv.org / master / db / d56 / tutorial_capture_graycode_pattern.html #gsc.tab = 0

它出现错误，如

 undefined reference to `cv::structured_light::GrayCodePattern::Params::Params()'

我该怎么办？

我在.pro

中添加了以下内容

INCLUDEPATH += /home/tau/opencv/opencv-3.1.0/include                   /home/tau/opencv/opencv_contrib/modules/structured_light/include
LIBS += -L/usr/local/lib -lopencv_core -lopencv_imgproc -lopencv_highgui -lopencv_imgcodecs -lopencv_video -lopencv_videoio-lopencv_structured_light
