Cross-compile Qt5 application from linux to windows

This approach uses statically linked qt, no .dlls are required

Steps

1. Compile qt and additional libraries with mxe.
   You can use prepared docker image:

docker build -t cross_compile -f Dockerfile.<version> .

If docker build reports errors when compiling packages, manually add problematic ones in dockerfile.

2. To simplify integration qml modules, use provided cmake file from OlivierLDff's project.
   Add his file and update your CMakeLists.txt

find_package(Qt5 QUIET COMPONENTS QmlWorkerScript)


get_target_property(QT_TARGET_TYPE Qt5::Core TYPE)
if(${QT_TARGET_TYPE} STREQUAL "STATIC_LIBRARY")
    include(<path to cmake with macro>)
    qt_generate_plugin_import(<target> VERBOSE)

    qt_generate_qml_plugin_import(<target>
    QML_SRC <path to qml resource>
    EXTRA_PLUGIN
        <extra plugins>
        # QtQuickVirtualKeyboardPlugin
        # QtQuickVirtualKeyboardSettingsPlugin
        # QtQuickVirtualKeyboardStylesPlugin
        # QmlFolderListModelPlugin
        # QQuickLayoutsPlugin
    VERBOSE
    )

endif()

if(TARGET Qt5::QmlWorkerScript)
    target_link_libraries(<target> PRIVATE Qt5::QmlWorkerScript)
endif()
