- Added ability to optionally skip SDK validation when making a Target instance even if we don't want to skip Target validation (used when we make the base UnrealEditor target to compare to project's Editor target - we don't need to manage SDK for that temporary UnrealEditor target). - ShaderCompileWorker is now BuildEnvironment.UniqueIfNeeded, which will build into the project binaries dir if needed (based on per-project SDK override) - UnrealPak is marked as not caring about an SDK versions so it can be built along with SCW that does care - Added $(BinaryDir) variable to UEBuildTarget, etc, for the location of the first Binary in the output binaries #rb David.Harvey, Joe.Kirchoff [CL 31661939 by josh adams in ue5-main branch]
