Building FactoryEditor...
[Upgrade]
[Upgrade] Using backward-compatible build settings. The latest version of UE sets the following values by default, which may require code changes:
[Upgrade]     bLegacyPublicIncludePaths = false                 => Omits subfolders from public include paths to reduce compiler command line length. (Previously: true).
[Upgrade]     ShadowVariableWarningLevel = WarningLevel.Error   => Treats shadowed variable warnings as errors. (Previously: WarningLevel.Warning).
[Upgrade]     PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs   => Set in build.cs files to enables IWYU-style PCH model. See https://docs.unrealengine.com/en-US/Programming/BuildTools/UnrealBuildTool/IWYU/index.html. (Previously: PCHUsageMode.UseSharedPCHs).
[Upgrade]     bLegacyParentIncludePaths = false                 => Omits module parent folders from include paths to reduce compiler command line length. (Previously: true).
[Upgrade]     CppStandard = CppStandardVersion.Default          => Updates C++ Standard to C++20 (Previously: CppStandardVersion.Cpp17).
[Upgrade]     WindowsPlatform.bStrictConformanceMode = true     => Updates MSVC strict conformance mode to true (Previously: false).
[Upgrade] Suppress this message by setting 'DefaultBuildSettings = BuildSettingsVersion.V4;' in FactoryEditor.Target.cs, and explicitly overriding settings that differ from the new defaults.
