Qt Visual Studio 插件bug处理

Only God knows how much time ive wasted on dealing it!!!

vs自动生成的cmakelists somehow在我的电脑上跑不成功, 无穷的debug之后发现, bug is:

你需要把vs自动生成的这段cmakelists ↓

target_link_libraries(QtLearning1
    PUBLIC
        Qt::Core
        Qt::Gui
        Qt::Widgets
)

改为

target_link_libraries(QtLearning1
    PUBLIC
        Qt5::Core
        Qt5::Gui
        Qt5::Widgets
)

或者

target_link_libraries(QtLearning1
    PUBLIC
        Qt${QT_VERSION_MAJOR}::Core
        Qt${QT_VERSION_MAJOR}::Gui
        Qt${QT_VERSION_MAJOR}::Widgets
)

同时 为了解决windows平台下dll复制的问题,即:

需要在cmakelists最后添加这段话:

if (WIN32 AND NOT DEFINED CMAKE_TOOLCHAIN_FILE)
    set(DEBUG_SUFFIX)
    if (MSVC AND CMAKE_BUILD_TYPE MATCHES "Debug")
        set(DEBUG_SUFFIX "d")
    endif ()
    set(QT_INSTALL_PATH "${CMAKE_PREFIX_PATH}")
    if (NOT EXISTS "${QT_INSTALL_PATH}/bin")
        set(QT_INSTALL_PATH "${QT_INSTALL_PATH}/..")
        if (NOT EXISTS "${QT_INSTALL_PATH}/bin")
            set(QT_INSTALL_PATH "${QT_INSTALL_PATH}/..")
        endif ()
    endif ()
    if (EXISTS "${QT_INSTALL_PATH}/plugins/platforms/qwindows${DEBUG_SUFFIX}.dll")
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E make_directory
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>/platforms/")
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E copy
                "${QT_INSTALL_PATH}/plugins/platforms/qwindows${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>/platforms/")
    endif ()
    foreach (QT_LIB Core Gui Widgets)
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E copy
                "${QT_INSTALL_PATH}/bin/Qt5${QT_LIB}${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>")
    endforeach (QT_LIB)
endif ()
