Hello EDK II community,
Our team is new to uefi development. We are gradually exploring the EDK II project. We have already successfully built default UEFI pauload (UefiPayloadPkg) for SBL. We are currently trying to add support for saving variables to NVRAM (ARIABLE_SUPPORT = SPI). It also requires enabling SMM and UNIVERSAL_PAYLOAD support. `The building by build -a IA32 -a X64 -p UefiPayloadPkg/UefiPayloadPkg.dsc -b DEBUG -t GCC5 -D BOOTLOADER=SBL` fails with the following message (full log is available in attachments):

Build environment: Linux-6.8.0-51-generic-x86_64-with-glibc2.35 Build start time: 13:55:06, Jan.20 2025 WORKSPACE = /home/user/edk2 EDK_TOOLS_PATH = /home/user/edk2/BaseTools CONF_PATH = /home/user/edk2/Conf PYTHON_COMMAND = python3 Processing meta-data . Architecture(s) = IA32 X64 Build target = DEBUG Toolchain = GCC5 Active Platform = /home/user/edk2/UefiPayloadPkg/UefiPayloadPkg.dsc build.py... /home/user/edk2/UefiPayloadPkg/UefiPayloadPkg.dsc(...): error 4000: Instance of library class [MmSaveStateLib] is not found in [/home/user/edk2/UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.inf] [X64] consumed by module [/home/user/edk2/UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.inf] - Failed - Build end time: 11:55:19, Jan.20 2025 Build total time: 00:00:01

It seems that some kind of dependency is not included to this configuration.
PiSmmCpuDxeSmm.inf is a part of UefiCpuPkg.dsc which has necessary inclusion:

UefiCpuPkg/PiSmmCpuDxeSmm/PiSmmCpuDxeSmm.inf { <Defines> FILE_GUID = B7242C74-BD21-49EE-84B4-07162E8C080D <LibraryClasses> SmmCpuFeaturesLib|UefiCpuPkg/Library/SmmCpuFeaturesLib/AmdSmmCpuFeaturesLib.inf MmSaveStateLib|UefiCpuPkg/Library/MmSaveStateLib/AmdMmSaveStateLib.inf }

We are use 0f3867fa6ef0553e26c42f7d71ff6bdb98429742 (edk2-stable202411) and 1301e0b47eb3b4212da384a34f23b68edaf1911e commits.
