    When I try to build my Unity project via script, the build process cannot find the file baselib.dll. I have the feeling that the path was set incorrectly in a build tool.

    Path where the baselib.dll cannot be found (during the build process):
    E:\UnityEditors\2021.1.24f1\Editor\Data\PlaybackEngines\MetroSupport\Players\UAP\il2cpp\Release\baselib.dll

    Path where the baselib.dll currently exists:
    E:\UnityEditors\2021.1.24f1\Editor\Data\PlaybackEngines\MetroSupport\Players\UAP\il2cpp\XXX\release\baselib.dll

    *XXX = ARM, ARM64, x64, x86


    Code (CSharp):
    1.       Time Compile: 26455 milliseconds Unity.TextMeshPro4.cpp
    2.       Time Compile: 25070 milliseconds System2.cpp
    3.       Time Compile: 24638 milliseconds Lump_libil2cpp_os.cpp
    4.       Time Compile: 22077 milliseconds Unity.TextMeshPro2.cpp

    From "Unity Data.vcxproj" file:

    Code (csharp):
    1. <None Include="$(UnityWSAPlayerDir)Players\UAP\il2cpp\$(PlatformTarget)\$(UnityPlayerConfiguration)\baselib.dll">
    Try also specifying "PlatformTarget" variable on the command line:

    Code (csharp):
    1. /p:PlatformTarget:x86

    I was having the same issue. I manually copied the master folder one level up in the directory structure so that the tool would find it.
    There's a command in the MRTK build window that has a wrong argument and don't know where that is coming from. Probably a bug in their code.
    Unfortunately I just start this project which is a handover from another vendor and updating Unity and MRTK versions is not a good idea right now...
