cmake 使用meta-qt 6的qml应用程序的Bitbake配方

我有一个非常简单的QML应用程序，我正试图用Yocto（Kirkstone）& meta-qt 6（开放源码）层构建它。我现在遇到了CMake的问题&我很确定这是因为我的CmakeLists.txt不正确，即。目标不会被建造。
如果任何人已经成功地编译与meta-qt 6在一个食谱，我会很感激任何指针！
我的食谱：

SUMMARY = "QT QML Test Recipe"
LICENSE = "CLOSED"

SRC_URI = "file://CMakeLists.txt        \
           file://CMakeLists.txt.user   \
           file://main.cpp              \
           file://Main.qml              \
          "

DEPENDS += " packagegroup-qt6-modules "

RDEPENDS_${PN} += "qtwayland"

S = "${WORKDIR}"

# Not needed as install is handled by cmake..
# do_install:append() {
#    install -d ${D}${bindir}
#    install -m 0755${WORKDIR}/build/qt-qml-demo ${D}${bindir}
#}

inherit qt6-cmake

项目布局：

├── files
│   ├── CMakeLists.txt
│   ├── CMakeLists.txt.user
│   ├── main.cpp
│   └── Main.qml
└── qt-qml-demo_0.1.bb

我的CmakeLists.txt：

cmake_minimum_required(VERSION 3.16)

project(qt-qml-demo VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

include(CMakePrintHelpers)

set(PROJECT_VERSION_MAJOR 6)
set(PROJECT_VERSION_MINOR 2)
set(PROJECT_VERSION 6.2.4)

cmake_print_variables(PROJECT_SOURCE_DIR)
cmake_print_variables(PROJECT_VERSION_MAJOR)
# Should output WORKDIR
cmake_print_variables(${S})

install(TARGETS qt-qml-demo
  RUNTIME DESTINATION "${S}"
  BUNDLE DESTINATION "${S}"
  LIBRARY DESTINATION "${S}"
)

set(CMAKE_AUTOMOC ON)

我的输出：

-- Detecting CXX compiler ABI info - done

我相信我有一个可行的解决方案。谢谢你的评论。项目布局现在是：

├── files
│   ├── CMakeLists.txt
│   ├── main.cpp
│   └── Main.qml
└── qt-qml-demo_0.1.bb

我的CmakeLists.txt

cmake_minimum_required(VERSION 3.16)

project(qml_demo VERSION 0.1 LANGUAGES CXX)

set(CMAKE_AUTOMOC ON)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

include(CMakePrintHelpers)

set(PROJECT_VERSION_MAJOR 6)
set(PROJECT_VERSION_MINOR 2)
set(PROJECT_VERSION 6.2.4)

# Seems to be important that 'find_package' comes before other calls below
find_package(Qt6
    CONFIG
    REQUIRED
    COMPONENTS
        BuildInternals
        Quick
        Core
        Qml
        Gui
)

qt_add_executable(app_qml_demo
    main.cpp
)

qt_add_qml_module(app_qml_demo
    URI qml_demo
    VERSION 1.0
    QML_FILES Main.qml
)

# Some of this below may not be required, to investigate
set_target_properties(app_qml_demo PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

target_link_libraries(app_qml_demo
    PRIVATE Qt6::Quick
)

install(TARGETS app_qml_demo
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR})

& qt-qml-demo_0.1.bb

SUMMARY = "QT QML Test Recipe"
LICENSE = "CLOSED"

SRC_URI = "file://CMakeLists.txt         \
           file://main.cpp              \
           file://Main.qml              "

DEPENDS += " qtbase \
             qtdeclarative-native \
             qtquick3d"

RDEPENDS_${PN} += "qtwayland"

S = "${WORKDIR}"

inherit qt6-cmake

这将创建一个成功填充到映像的二进制文件。唯一突出的问题是main.cpp使用了不恰当的文件路径方法：

QUrl url(u"qrc:/qt-qml-demo/Main.qml"_qs);

这在嵌入式目标（RPi 4）上不起作用。这应该是一个简单的修复，任何感兴趣的人都应该在未来的某个时候找到一个更新的配方here。
我相信这个答案可以改进，我会很高兴任何投入，但至少这可能是一个起点，为他人。
