鏈接OpenCV gpu :: Stereo示例時出錯
[英]Error linking OpenCV gpu::Stereo sample
問題描述
我正在嘗試編譯opencv-3.0.0-beta/samples/gpu/stereo_match.cpp但是opencv-3.0.0-beta/samples/gpu/stereo_match.cpp一些鏈接錯誤：

我正在使用Qt Creator 4.0.2和本文在OSX上為OpenCV配置Qt的項目文件。 我已經按照指南通過自制軟件安裝了OpenCV 3.0：

據我所知，我已經在CUDA中安裝了opencv 3.0，並且正在鏈接庫，但是我不確定為什么這些符號似乎丟失了。
如何再次檢查我是否正確鏈接？
鏈接和編譯此示例的正確方法是什么？

感謝Miki的技巧（明確地），我設法編譯了示例，但是僅通過命令來編譯：

大多數include和library標志是通過pkg-config生成的：
pkg-config --libs --cflags /usr/local/Cellar/opencv3/3.1.0_3/lib/pkgconfig/opencv.pc
我只需要手動添加以下路徑：
-L/usr/local/Cellar/opencv3/3.1.0_3/share/OpenCV/3rdparty/lib
由於先前的錯誤：
ld: library not found for -lippicv
