+    - `QT_MODULES` *(required)* - The Qt modules to link to. Specify the corresponding CMake targets here.
+    - `CXX_QT_EXPORT_DIR` (optional) - Manually specify the path where CXX-Qt artifacts will be exported to.
         - This is usually not necessary. However, if you're importing the same crate with different feature sets in the same CMake build configuration, you will need to specify seperate `CXX_QT_EXPORT_DIR`s to avoid multiple versions of the crate exporting to the same directory.

 2. `cxx_qt_import_qml_module` - This function imports a QML modules as a new target. It requires the following arguments:
     - `TARGET_NAME` - Specify the name of the CMake target that this function will create
     - `URI` - The URI of the qml module to import - this needs to exactly match the URI in the `CxxQtBuilder::qml_module` call in your build script.
