解释下后面的依托：

if (WIN32 AND NOT DEFINED CMAKE_TOOLCHAIN_FILE)
    set(DEBUG_SUFFIX)
    if (MSVC AND CMAKE_BUILD_TYPE MATCHES "Debug")
        set(DEBUG_SUFFIX "d")

    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}>/plugins/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}>/plugins/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/Qt6${QT_LIB}${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>")
    endforeach (QT_LIB)
endif ()

复制 foreach (QT_LIB Core Gui Widgets)里的.dll和plugun/windows.dll,并不好用,建议用toolChain

file(GLOB DLL_FILES "${CLION_INSTALL_PATH}/bin/mingw/bin/*.dll")

foreach(DLL_FILE ${DLL_FILES})
    file(COPY ${DLL_FILE} DESTINATION ${CMAKE_BINARY_DIR})
endforeach()

复制链接库

如果要分文件夹：

add_subdirectory(src)
add_subdirectory(resources)

./src:

set(PROJECT_SOURCES
        main.cpp
)

qt_add_executable(${projectName}
#                MANUAL_FINALIZATION
        ${PROJECT_SOURCES}
)

./resources:

set(SOURCES_FILES
        ic.png
        ico.ico
)
foreach (file ${SOURCES_FILES})
    configure_file(${file} ${CMAKE_CURRENT_BINARY_DIR}/${file} COPYONLY)
endforeach ()
