We are building our game nightly using GitHub version of the engine (4.13) like this:

```
RunUAT BuildCookRun -project=D:\Project\Project.uproject -build -noP4 -platform=Win64 -clientconfig=Test -serverconfig=Test -cook -Compressed -allmaps -stage -pak -archive 

```

and it works fine. But when we try to use the same line with launcher version of the engine we get a following error on a build stage:

```
...
UnrealBuildTool: [135/135] Link Insomnia_v2-Win64-Test.exe
UnrealBuildTool: LINK : fatal error LNK1181: cannot open input file 'E:\_UE4_Launcher\UE_4.13\Engine\Binaries\Win64\UE4-Launch-Win64-Test.lib'
UnrealBuildTool: ERROR: UBT ERROR: Failed to produce item: E:\_insomnia\Binaries\Win64\Insomnia_v2-Win64-Test.exe

```

Could you elaborate on this linking error?
