Thanks for reporting! It appears this is similar to #522: using CMake 3.30 or newer to compile prints this warning.

To resolve this the CMakeLists.txt files for Linux and Windows for the Flutter plugins need to be migrated.

However, note that using FetchContent_MakeAvailable requires CMake 3.14. Check if supporting old versions like it is required and add a fallback to the old call.
