cmake output

The following configure command fails:

] CC=/usr/lib/ccache/bin/gcc CXX=/usr/lib/ccache/bin/g++ cmake -DPORT=WPE -DCMAKE_INSTALL_PREFIX=/home/user/Install/packages/wpewebkit -DENABLE_WPE_QT_API=ON -DENABLE_JOURNALD_LOG=OFF .. -GNinja -DCMAKE_BUILD_TYPE=Release -DUSE_LIBBACKTRACE=OFF -DENABLE_WPE_PLATFORM=ON -DENABLE_WPE_1_1_API=OFF

(see attachment for output)

I am on Gentoo GNU/Linux with qtdeclarative 6.10.2 . In my /usr/lib64/cmake/Qt6Quick/Qt6QuickConfig.cmake there is relevant code for finding Qt6QuickPrivate, but obviously it is not enabled:

# Find the private module counterpart.
set(__qt_Quick_always_load_private_module OFF) # <------------------- (1)
include("${CMAKE_CURRENT_LIST_DIR}/Qt6Quick-build.cmake" OPTIONAL)
if (Qt6Quick_FOUND
        AND NOT Qt6QuickPrivate_FOUND
        AND NOT FALSE
        AND (
            __qt_Quick_always_load_private_module # <------------- (1)
            OR DEFINED QT_REPO_MODULE_VERSION # <------------ other comments indicate this is only for building Qt
            OR QT_FIND_PRIVATE_MODULES # <------------ (2)
        )
    )
    if("${_qt_cmake_dir}" STREQUAL "")
        set(_qt_cmake_dir "${QT_TOOLCHAIN_RELOCATABLE_CMAKE_DIR}")
    endif()
    set(__qt_use_no_default_path_for_qt_packages "NO_DEFAULT_PATH")
    if(QT_DISABLE_NO_DEFAULT_PATH_IN_QT_PACKAGES)
        set(__qt_use_no_default_path_for_qt_packages "")
    endif()
    find_package(Qt6QuickPrivate "6.10.2" EXACT
        QUIET
        CONFIG
        PATHS
            ${QT_BUILD_CMAKE_PREFIX_PATH}
            "${CMAKE_CURRENT_LIST_DIR}/.."
            "${_qt_cmake_dir}"
            ${_qt_additional_packages_prefix_paths}
        ${__qt_use_no_default_path_for_qt_packages}
    )

    if(NOT Qt6QuickPrivate_FOUND)
        get_property(Qt6QuickPrivate_warning_shown GLOBAL PROPERTY
            Qt6QuickPrivate_warning_shown
        )
        if(NOT Qt6QuickPrivate_warning_shown)
            message(VERBOSE
                "The private module package 'Qt6QuickPrivate' "
                "could not be found. It possibly needs to be installed separately with your "
                "package manager."
            )
            set_property(GLOBAL PROPERTY
                Qt6QuickPrivate_warning_shown ON
            )
        endif()
    endif()
endif()
unset(__qt_Quick_always_load_private_module)

------
(1) is always false (maybe it is different on other distributions?), and (2) is not defined anywhere in WebKit repo, so finding Qt6Quick does not find Qt6QuickPrivate on my system.
