我正在嘗試使用深度傳感器（PMD Camboard），並嘗試將捕獲的深度圖像顯示爲實時流。我可以從傳感器獲取數據。一旦我嘗試投入OpenCV部件，問題就會開始。單獨他們完美地工作，但一旦我嘗試整合它們，問題就會開始。我認爲錯誤與CMakeLists.txt有關，因爲即使我試圖編譯一個簡單的程序，只顯示攝像頭源，沒有任何depthsensor的東西，我也會得到同樣的錯誤。當我嘗試使用openCV的CMake進行編譯時，上述程序起作用。OpenCV Qt未定義的參考錯誤，同時編譯
編輯：我試過系統禁用的CMake的部分，看看哪些部分恰好觸發錯誤，發現行：
link_directories(${royale_LIB_DIR})
是導致錯誤的一個。
我收到以下錯誤，當我嘗試編譯：
/usr/local/lib/libopencv_highgui.so.3.1.0: undefined reference to `QWidget::isFullScreen() [email protected]_5'
/usr/local/lib/libopencv_cvv.so.3.1.0: undefined reference to `QAbstractSlider::setMinimum(int)@Qt_5'

而我的CMakeLists.txt如下：
cmake_minimum_required(VERSION 2.8)
set(CMAKE_PREFIX_PATH "share")
#project (depthDataCallBack)
project (webStream)
find_package(OpenCV REQUIRED)
find_package(royale REQUIRED)
link_directories(${royale_LIB_DIR})
include_directories(${CMAKE_CURRENT_SOURCE_DIR}/inc)
add_executable(webStream webStream.cpp)
target_link_libraries(webStream ${OpenCV_LIBS})
target_link_libraries(webStream "${royale_LIBS}")
我是新CMake，只有recently corrected。任何幫助，將不勝感激。
