Solved. The clang compiler is incompatible with the plugin currently and was preventing the build. In case it is still useful, Visual Studio returned the following build errors: 1>Using Clang 14.0.5 compiler (C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\Llvm) with Visual Studio 2022 14.33.31630 runtime (C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.33.31629) and Windows 10.0.19041.0 SDK (C:\Program Files (x86)\Windows Kits\10). 1>[Upgrade] 1>[Upgrade] Using backward-compatible include order.

Hi Nick,

Developing with Unreal Engine requires Visual Studio on Windows.

You can find ArcGIS Maps SDK for Unreal Engine's system requirements at https://developers.arcgis.com/unreal-engine/reference/system-requirements/

And there is documentation from Unreal Engine about setting up Visual Studio at https://docs.unrealengine.com/5.1/en-US/setting-up-visual-studio-development-environment-for-cplusplus-projects-in-unreal-engine/

Hope it helps,

I followed the instructions provided on https://developers.arcgis.com/unreal-engine/ to the best of my ability. I am using the clang compiler, maybe that is related to these issues?
