Because the plugin is precompiled and contains a large number of C++ link symbols and debug symbols, it will cost 10G disk space after decompression (most files are UE-generated binaries in Intermediate).
Don't need to worry about disk usage, this is just disk usage during development, after the project is packaged, the plug-in disk usage is 300M only (most files are GStreamer dynamic library and speech models).

The license file will be published in the discussion, and the plugin package file will automatically include an license file.
