We are currently using the auto setup and live link plugins for Unreal from iClone. We have made modifications to the Unreal engine. At present, during the compilation process of the Unreal engine, it is necessary to compile the related iClone plugins. However, we are unable to compile some of the dll files of the plugins. Can you provide the source code for this part?

Steps to reproduce issue:
1.build unreal engine source code with this plugin
2.There are only DLL and PDB files but no source files.

Expected Result:
Can you provide the source code for this part?
