Builds the UE project with proper configuration.
Read the effective Cortex config to get the engine path:
.cortex/config.yaml.cortex/config.local.yaml over it for per-machine overrides$UE_PATH only when project config does not provide engine.pathUse the shared loader when available:
python cortex-toolkit/lib/cortex_config.py --project-dir . --get engine.path
Find the .uproject file in the project root.
Execute the build command:
"$ENGINE_PATH/Engine/Binaries/DotNET/UnrealBuildTool/UnrealBuildTool.exe" \
<ProjectName>Editor Win64 Development \
-Project="<absolute path to .uproject>" \
-WaitMutex -FromMsBuild
