Неопределенная ошибка ссылки на QQuickWindow от cmake

Question

Я нахожусь в середине интегрированного проекта catkin с проектом qt-quick. Я сделал прочный CMakeLists.txt:

cmake_minimum_required (VERSION 2.8) 
project (qml_ros_camera) 

set(CMAKE_AUTOMOC ON) 

find_package(Qt5Core REQUIRED) 

set(CMAKE_CXX_FLAGS_COVERAGE "${CMAKE_CXX_FLAGS_RELEASE} -fprofile-arcs -ftest-coverage") 

# set up a mapping so that the Release configuration for the Qt imported target is 
# used in the COVERAGE CMake configuration. 
set_target_properties(Qt5::Core PROPERTIES MAP_IMPORTED_CONFIG_COVERAGE "RELEASE") 

get_target_property(QtCore_location Qt5::Core LOCATION) 

find_package(Qt5 COMPONENTS Quick Core Network) 
find_package(Qt5Widgets REQUIRED) 
find_package(Qt5Declarative) 

catkin_package() 

include_directories(include ${OpenCV_INCLUDE_DIRS}) 

set(CMAKE_INCLUDE_CURRENT_DIR ON) 
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11") 
set(HEADER_FILES ~/image_transport_ws/src/qml_ros_camera/src/videoplayer.h) 
set(SOURCE_FILES ~/image_transport_ws/src/qml_ros_camera/src/main.cpp 
    ~/image_transport_ws/src/qml_ros_camera/src/videoplayer.cpp 
    ) 

set(qml_ros_camera_RESOURCES qml.qrc) 
qt5_add_resources(qml_ros_camera_RESOURCES_RCC ${qml_ros_camera_RESOURCES}) 

add_executable(qml_ros_camera 
    ${SOURCE_FILES} 
    ${qml_ros_camera_RESOURCES_RCC}) 

target_link_libraries(qml_ros_camera ${Qt5Widgets_LIBRARIES} 
    ${Qt5Core} 
    ${Qt5Declarative_LIBRARIES} 
    ${catkin_LIBRARIES} ${OpenCV_LIBRARIES}) 

include_directories(
    ~/image_transport_ws/src/qml_ros_camera/src/ 
    /opt/Qt/5.5/gcc_64/include/QtQuick 
    /opt/Qt/5.5/gcc_64/include/QtCore 
    ${Qt5Declarative_INCLUDE_DIRS} 
    ${Qt5Widgets_INCLUDE_DIRS}) 

include_directories(${Qt5Widgets_INCLUDE_DIRS}) 

add_definitions(${Qt5Widgets_DEFINITIONS}) 

ADD_DEFINITIONS(${QT_DEFINITIONS}) 
qt5_use_modules(qml_ros_camera Widgets Qml) 

ошибка компиляции У меня есть:

CMakeFiles/qml_ros_camera.dir/src/main.cpp.o: 
In function `QQuickWindow* qobject_cast<QQuickWindow*>(QObject*)': main.cpp: 
(.text._Z12qobject_castIP12QQuickWindowET_P7QObject 
[_Z12qobject_castIP12QQuickWindowET_P7QObject]+0x16) 
: undefined reference to `QQuickWindow::staticMetaObject' 

Я использую Qt-творец и C++. Проблема связана с моим плохим пониманием того, как работает CMakeLists.txt. Как я могу исправить эту ужасную ошибку компиляции?

Answer 1

Try связь так:

target_link_libraries(... 
    Qt5::Core 
    Qt5::Quick 
    ... 

И вам не нужно include_directories/add_definitions для кварт материала.
