### Preliminary Checks - [X] This issue is not a duplicate. Before opening a ne…w issue, please search existing issues. - [X] This issue is not a question, feature request, or anything other than a bug report directly related to this project. ### Description The ZEDLiveLink.uplugin does not build on my Arch x64 machine. I have followed the instructions on the README to no avail. I setup an Unreal project (using version 5.3.2), create the Plugins folder and move the ZEDLiveLink folder inside. Unreal outputs: LogLinux: Warning: MessageBox: The following modules are missing or built with a different engine version: ZEDLiveLink ZEDLiveLinkEditor Would you like to rebuild them now?: Missing new_test Modules: No is implied. I then try to manually build using UAT, with the following command: `/home/<user>/bin/Linux_Unreal_Engine/Engine/Build/BatchFiles/RunUAT.sh BuildPlugin -plugin=/home/<user>/Downloads/zed-livelink-4.2.0/ZEDLiveLink/ZEDLiveLink.uplugin -package=/home/<user>/Downloads/zed-livelink-4.2.0/ZEDLiveLink/output` Which in turn outputs: `Building UnrealEditor...

Using v4.0.8, I can setup an Unreal project via your examples, connect the LiveLink bus and everything works as it should. ### Steps to Reproduce 1. Download the ZEDLiveLink Unreal Engine plugin. 2. Create an Unreal Engine 5.3 blank project and copy the plugin to the Plugins folder 3. Unreal won't build the plugin, try to build manually using UAT 4. Errors in: ZEDLiveLinkPose.cpp:19:5, AnimNode_ZEDLiveLinkPose.cpp:19:5, AnimNode_ZEDLiveLinkPose.cpp:23:5 5. Build is not successful. ... ### Expected Result The plugin should be able to be built on Linux systems ### Actual Result The plugin is not built successfully. ### ZED Camera model ZED2i ### Environment ```shell OS: Arch Linux x64 GPU: NVidia RTX 3060 ZED SDK: 4.2.0 (also occurs with 4.1.0, v4.0.8 works) RAM: 32GB ``` ### Anything else? _No response_

Would really appreciate any help.
Thanks.
