无法使用Qt图表- QT6 | Cmake

Question

我正在使用Qt 6.2.1和cmake，但我找不到使用Qt图表的方法。

Qt图表安装在"C:\Qt\6.2.1\Src\qtcharts“下

在我的cmakelists.txt中，我包含了find_package和target_link_libraries中的Qt图表。这似乎适用于qt5 (在StackOverflow的其他答案中找到)，但不适用于qt6。(我已经隐藏了项目源代码文件)

cmake_minimum_required(VERSION 3.5)

project(projectname VERSION 0.1 LANGUAGES CXX)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOUIC ON)
set(CMAKE_AUTOMOC ON)
set(CMAKE_AUTORCC ON)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

set(CMAKE_CXX_FLAGS_DEBUG "/MDd")

find_package(QT NAMES Qt6 COMPONENTS Widgets Charts REQUIRED)
find_package(Qt${QT_VERSION_MAJOR} COMPONENTS Xml Widgets REQUIRED)

set(PROJECT_SOURCES
        ...
)

if(${QT_VERSION_MAJOR} GREATER_EQUAL 6)
    qt_add_executable(projectname
        MANUAL_FINALIZATION
        ${PROJECT_SOURCES}
    )
else()
    add_executable(projectname 
        ${PROJECT_SOURCES}
    )
endif()

target_link_libraries(projectname PRIVATE Qt${QT_VERSION_MAJOR}::Widgets Qt${QT_VERSION_MAJOR}::Xml Qt6::Charts)

if(QT_VERSION_MAJOR EQUAL 6)
    qt_finalize_executable(projectname)
endif()

我得到了这个错误：

C:\Qt\6.2.1\msvc2019_64\lib\cmake\Qt6Core\Qt6CoreMacros.cmake:559: error: Target "projectname" links to target "Qt6::Charts" but the target was not found.  Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? C:/Qt/6.2.1/msvc2019_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:523 (_qt_internal_create_executable) C:/Qt/6.2.1/msvc2019_64/lib/cmake/Qt6Core/Qt6CoreMacros.cmake:847 (qt6_add_executable) CMakeLists.txt:78 (qt_add_executable)

解决方案(感谢@vre)：

我必须选择6.2.1下的Qt图表，而不是在线安装程序中的Qt
