    \title Export Item
    \brief Exports dependencies and properties to other products.

    An \c Export item can appear inside a \l{Product Item}. It defines a Module with the product's
    name that can be depended on by other products.
    The properties attached to the Export item will take effect in all products that depend on the
    product inside which the Export item is defined.
    As an example, consider these two products:
    \code
    Product {
        name: "A"
        Export {
            Depends { name: "cpp" }
            cpp.includePaths: product.sourceDirectory
            cpp.defines: ["USING_" + product.name.toUpperCase()]
        }
    }

    Product {
        name: "B"
        Depends { name: "A" }
    }
    \endcode

    The sources in product B will be able to use headers from product A without specifiying
    the full path to them, because the include path has been made known to the compiler via
    A's Export item. Additionally, product B will be compiled with the define \c{USING_A}.

    \note This relationship is transitive, so a product C depending on product B will also
    get the include paths and preprocessor macros via A's Export item.

    In contrast to Module items, \c{product} within Export items refers to the product which defines
    the Export item. Use the \c{importingProduct} variable to refer to the product that
    pulls in the resulting module.
