I am trying to upgrade the Unity Asset Transformer from version 2024.3.0.14 to 2025.3.0.0 using the Python installation package (whl). I noticed that the latest version requires installing additional packages such as imgui-bundle, ninja, and libx11-dev. It also attempts to clone freetype-populate from [GitHub - freetype/freetype: Official mirror of https://gitlab.freedesktop.org/freetype/freetype].
I am building the Docker image in an restricted environment without GitHub access. Is it really necessary to include the GUI-related components in the SDK? Are these additional packages truly required for the latest Unity Asset Transformer?
