Google has informed developers of a vulnerability in versions (earlier than M102) of WebRTC. Impacts, workarounds, and updates can be found here.
In addition to being added to the generated Unreal Engine (UE) project under the Config/UnrealBuildTool folder, Unreal Build Tool (UBT) reads settings from XML config files in the following locations on Windows:
-
Engine/Saved/UnrealBuildTool/BuildConfiguration.xml -
USER/AppData/Roaming/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml -
My Documents/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
On Linux and Mac, the following paths are used instead:
-
/Users/USER/.config//Unreal Engine/UnrealBuildTool/BuildConfiguration.xml -
/Users/USER/Unreal Engine/UnrealBuildTool/BuildConfiguration.xml
Keep reading to learn more about the following properties, which help to set and customize build configurations.
BuildConfiguration
$ bIgnoreOutdatedImportLibraries : Whether to ignore import library files that are out of date when building targets. Set this to true to improve iteration time. By default, we do not bother re-linking targets if only a dependent .lib file has changed, as chances are that the import library was not actually different unless a dependent header file of this target was also changed, in which case the target would automatically be rebuilt.
$ bPrintDebugInfo : Whether debug info should be written to the console.
$ bAllowHybridExecutor : Whether the hybrid executor will be used (a remote executor and local executor).
$ bAllowHordeCompute : Whether Horde remote compute may be used. (Highly experimental, disabled by default.)
$ bAllowXGE : Whether XGE may be used.
$ bAllowFASTBuild : Whether FASTBuild may be used.
$ bAllowSNDBS : Whether SN-DBS may be used.
$ bUseUBTMakefiles : Enables support for very fast iterative builds by caching target data. Turning this on causes Unreal Build Tool (UBT) to emit 'UBT Makefiles' for targets when they are built the first time. Subsequent builds will load these Makefiles and begin outdatedness checking and build invocation very quickly. The caveat is that if source files are added or removed to the project, UBT will need to gather information about those in order for your build to complete successfully. Currently, you must run the project file generator after adding/removing source files to tell UBT to re-gather this information.
- Events that can invalidate the 'UBT Makefile':
Adding/removing
.cppfiles. Adding/removing.hfiles with UObjects. Adding new UObject types to a file that did not previously have any. Changing global build settings (most settings in this file qualify). Changed code that affects how Unreal Header Tool (UHT) works. You can force regeneration of the 'UBT Makefile' by passing the-gatherargument, or simply regenerating project files. * This also enables the fast include file dependency scanning and caching system that allows Unreal Build Tool to detect out of date dependencies very quickly. When enabled, a deep C++ include graph does not have to be generated, and instead, we only scan and cache indirect includes for after a dependent build product was already found to be out of date. During the next build, we will load those cached indirect includes and check for outdatedness.
$ MaxParallelActions : Number of actions that can be executed in parallel. If 0 then code will pick a default based on the number of cores and memory available. Applies to the ParallelExecutor, HybridExecutor, and LocalExecutor.
$ bAllCores : Consider logical cores when determining how many total CPU cores are available.
$ bCompactOutput : Instruct the executor to write compact output (for example, only errors), if supported by the executor. This field is used to hold the value when specified from the command line or XML.
$ bDebugBuildsActuallyUseDebugCRT : Enables the debug C++ runtime (CRT) for debug builds. By default we always use the release runtime, since the debug version isn't particularly useful when debugging Unreal Engine projects, and linking against the debug CRT libraries forces our third party library dependencies to also be compiled using the debug CRT (and often perform more slowly). Often it can be inconvenient to require a separate copy of the debug versions of third party static libraries simply so that you can debug your program's code.
$ bLegalToDistributeBinary : Whether the output from this target can be publicly distributed, even if it has dependencies on modules that are in folders with special restrictions (for example, CarefullyRedist, NotForLicensees, NoRedist).
$ bUseInlining : Enable inlining for all modules.
$ bUseDebugLiveCodingConsole : Whether to enable support for live coding.
$ bUseXGEController : Whether the XGE controller worker and modules should be included in the engine build. These are required for distributed shader compilation using the XGE interception interface.
$ bUseUnityBuild : Whether to unify C++ code into larger files for faster compilation.
$ bForceUnityBuild : Whether to force C++ source files to be combined into larger files for faster compilation.
$ bMergeModuleAndGeneratedUnityFiles : Whether to merge the module and generated unity files for faster compilation.
$ bUseAdaptiveUnityBuild : Use a heuristic to determine which files are currently being iterated on and exclude them from unity blobs, resulting in faster incremental compile times. The current implementation uses the read-only flag to distinguish the working set, assuming that files will be made writable by the source control system if they are being modified. This is true for Perforce, but not for Git.
$ bAdaptiveUnityDisablesOptimizations : Disable optimization for files that are in the adaptive non-unity working set.
$ bAdaptiveUnityDisablesPCH : Disables force-included Precompiled Headers (PCHs) for files that are in the adaptive non-unity working set.
$ bAdaptiveUnityDisablesProjectPCHForProjectPrivate : Backing storage for bAdaptiveUnityDisablesProjectPCH.
$ bAdaptiveUnityCreatesDedicatedPCH : Creates a dedicated PCH for each source file in the working set, allowing faster iteration on cpp-only changes.
$ bAdaptiveUnityEnablesEditAndContinue : Creates a dedicated PCH for each source file in the working set, allowing faster iteration on cpp-only changes.
$ bAdaptiveUnityCompilesHeaderFiles : Creates a dedicated source file for each header file in the working set to detect missing includes in headers.
$ MinGameModuleSourceFilesForUnityBuild : The number of source files in a game module before unity build will be activated for that module. This allows small game modules to have faster iterative compile times for single files, at the expense of slower full rebuild times. This setting can be overridden by the bFasterWithoutUnity option in a module's .Build.cs file.
$ DefaultWarningLevel : Default treatment of uncategorized warnings
$ DeprecationWarningLevel : Level to report deprecation warnings as errors
$ bWarningsAsErrors : Whether to enable all warnings as errors. UE enables most warnings as errors already, but disables a few (such as deprecation warnings).
$ UnsafeTypeCastWarningLevel : Indicates what warning/error level to treat unsafe type casts as on platforms that support it (for example, double->float or int64->int32).
$ bUndefinedIdentifierErrors : Forces the use of undefined identifiers in conditional expressions to be treated as errors.
$ bRetainFramePointers : Forces frame pointers to be retained. This is usually required when you want reliable callstacks (for example, mallocframeprofiler).
$ bUseFastMonoCalls : New Monolithic Graphics drivers have optional "fast calls" replacing various D3d functions.
$ NumIncludedBytesPerUnityCPP : An approximate number of bytes of C++ code to target for inclusion in a single unified C++ file.
$ bStressTestUnity : Whether to stress test the C++ unity build robustness by including all C++ files files in a project from a single unified file.
$ bDetailedUnityFiles : Whether to add additional information to the unity files, such as '_of_X' in the file name.
$ bDisableDebugInfo : Whether to globally disable debug info generation; see DebugInfoHeuristics.cs for per-config and per-platform options.
$ bDisableDebugInfoForGeneratedCode : Whether to disable debug info generation for generated files. This improves link times for modules that have a lot of generated glue code.
$ bOmitPCDebugInfoInDevelopment : Whether to disable debug info on PC/Mac in development builds (for faster developer iteration, as link times are extremely fast with debug info disabled).
$ bUsePDBFiles : Whether PDB files should be used for Visual C++ builds.
$ bUsePCHFiles : Whether PCH files should be used.
$ bDeterministic : Set flags required for deterministic linking (experimental, may not be fully supported). Deterministic compiling is controlled via ModuleRules.cs.
$ bForceDeterministic : Force set flags required for deterministic compiling and linking (experimental, may not be fully supported). This setting is only recommended for testing, instead:
Set bDeterministic on a per module basis in ModuleRules.cs to control deterministic compiling.
Set bDeterministic on a per target basis in TargetRules.cs to control deterministic linking.
$ bPreprocessDepends : Generate dependency files by preprocessing. This is only recommended when distributing builds as it adds additional overhead.
$ StaticAnalyzer : Whether static code analysis should be enabled.
$ StaticAnalyzerOutputType : The output type to use for the static analyzer. This is only supported for Clang.
$ StaticAnalyzerMode : The mode to use for the static analyzer. This is only supported for Clang. Shallow mode completes quicker but is generally not recommended.
$ MinFilesUsingPrecompiledHeader : The minimum number of files that must use a pre-compiled header before it will be created and used.
$ bForcePrecompiledHeaderForGameModules : When enabled, a precompiled header is always generated for game modules, even if there are only a few source files in the module. This greatly improves compile times for iterative changes on a few files in the project, at the expense of slower full rebuild times for small game projects. This can be overridden by setting MinFilesUsingPrecompiledHeaderOverride in a module's Build.cs file.
$ bUseIncrementalLinking : Whether to use incremental linking or not. Incremental linking can yield faster iteration times when making small changes. Currently disabled by default because it tends to behave a bit buggy on some computers (PDB-related compile errors).
$ bAllowLTCG : Whether to allow the use of link time code generation (LTCG).
$ bPreferThinLTO : When Link Time Code Generation (LTCG) is enabled, whether to prefer using the lighter weight version on supported platforms.
$ bPGOProfile : Whether to enable Profile Guided Optimization (PGO) instrumentation in this build.
$ bPGOOptimize : Whether to optimize this build with Profile Guided Optimization (PGO).
$ bSupportEditAndContinue : Whether to support edit and continue. Only works on Microsoft compilers.
$ bOmitFramePointers : Whether to omit frame pointers or not. Disabling is useful, for example, for memory profiling on the PC.
$ bUseMallocProfiler : If true, then enable memory profiling in the build (defines USE_MALLOC_PROFILER=1 and forces bOmitFramePointers=false).
$ bUseSharedPCHs : Enables "Shared PCHs", a feature which significantly speeds up compile times by attempting to share certain PCH files between modules that UBT detects are including those PCH's header files.
$ bUseShippingPhysXLibraries : True if Development and Release builds should use the release configuration of PhysX/APEX.
$ bUseCheckedPhysXLibraries : True if Development and Release builds should use the checked configuration of PhysX/APEX. if bUseShippingPhysXLibraries is true this is ignored.

$ bIncludeTemplateFiles : True if we should include template files in the generated project.
$ bIncludeEnginePrograms : True if we should include program projects in the generated solution.
$ IncludeCppSource : Whether to include C++ targets.
$ bIncludeDotNetPrograms : True if we should include csharp program projects in the generated solution. Pass "-DotNet" to enable this.
$ PrimaryProjectName : Name of the primary project file - for example, the base file name for the Visual Studio solution file, or the Xcode project file on Mac.

VCProjectFileGenerator
$ Version : The version of Visual Studio to generate project files for.
$ MaxSharedIncludePaths : Puts the most common include paths in the IncludePath property in the MSBuild project. This significantly reduces Visual Studio memory usage (measured 1.1GB -> 500mb), but seems to be causing issues with Visual Assist. Value here specifies maximum length of the include path list in KB.
$ ExcludedIncludePaths : Semi-colon separated list of paths that should not be added to the projects include paths. Useful for omitting third-party headers (for example, ThirdParty/WebRTC) from intellisense suggestions and reducing memory footprints.
$ ExcludedFilePaths : Semi-colon separated list of paths that should not be added to the projects. Useful for omitting third-party files (for example, ThirdParty/WebRTC) from intellisense suggestions and reducing memory footprints.
$ bBuildUBTInDebug : Forces Unreal Build Tool (UBT) to be built in debug configuration, regardless of the solution configuration.
$ bBuildLiveCodingConsole : Whether to include a dependency on LiveCodingConsole when building targets that support live coding.
$ bIncludeDocumentation : True if we should include documentation in the generated projects.
$ bUsePrecompiled : True if build targets should pass the -useprecompiled argument.
$ bIncludeEngineSource : True if we should include engine source in the generated solution.
$ bIncludeShaderSource : True if shader source files should be included in generated projects.
$ bIncludeConfigFiles : True if we should include config (.ini) files in the generated project.
$ bIncludeTemplateFiles : True if we should include template files in the generated project.
$ bIncludeEnginePrograms : True if we should include program projects in the generated solution.
$ IncludeCppSource : Whether to include C++ targets.
$ bIncludeDotNetPrograms : True if we should include csharp program projects in the generated solution. Pass "-DotNet" to enable this.
$ PrimaryProjectName : Name of the primary project file - for example, the base file name for the Visual Studio solution file, or the Xcode project file on Mac.
$ bPrimaryProjectNameFromFolder : If true, sets the primary project name according to the name of the folder it is in.
XcodeProjectFileGenerator
$ bIncludeDocumentation : True if we should include documentation in the generated projects.

$ bIncludeConfigFiles : True if we should include config (.ini) files in the generated project.
$ bIncludeTemplateFiles : True if we should include template files in the generated project.
$ bIncludeEnginePrograms : True if we should include program projects in the generated solution.
$ IncludeCppSource : Whether to include C++ targets
$ bIncludeDotNetPrograms : True if we should include csharp program projects in the generated solution. Pass -DotNet to enable this.
$ PrimaryProjectName : Name of the primary project file - for example, the base file name for the Visual Studio solution file, or the Xcode project file on Mac.
$ bPrimaryProjectNameFromFolder : If true, sets the primary project name according to the name of the folder it is in.
SourceFileWorkingSet
$ Provider : Sets the provider to use for determining the working set.
$ RepositoryPath : Sets the path to use for the repository. Interpreted relative to the Unreal Engine root directory (the folder above the Engine folder) - if relative.
$ GitPath : Sets the path to use for the Git executable. Defaults to "git" (assuming it is in the PATH).
RemoteMac
$ ServerName : These two variables will be loaded from the XML config file in XmlConfigLoader.Init().
$ UserName : The remote username.
$ SshPrivateKey : If set, instead of looking for RemoteToolChainPrivate.key in the usual places (Documents/Unreal, Engine/UnrealBuildTool/SSHKeys or Engine/Build/SSHKeys), this private key will be used.
$ RsyncAuthentication : The authentication used for Rsync (for the -e rsync flag).
$ SshAuthentication : The authentication used for SSH (similar to RsyncAuthentication).
HoloLensPlatform
$ Compiler : Version of the compiler toolchain to use on HoloLens. A value of "default" will be changed to a specific version at UBT startup.
Log
$ bBackupLogFiles : Whether to backup an existing log file, rather than overwriting it.
$ LogFileBackupCount : The number of log file backups to preserve. Older backups will be deleted.
