Subject: [PATCH] CMake: Check CMAKE_CONFIGURATION_TYPES when doing automoc
 extraction

Otherwise when configuring a standalone example without specifying a
CMAKE_BUILD_TYPE (so it's empty), building fails because
qt6_generate_meta_types_json_file thinks it's being called with
a multi-config generator.
