Sadly, nmake can't be told to show the full command they execute for
makefiles generated with cmake. Otherwise it would be obvious to know
the involved steps for building a component.

First of all, use /MDd (for debug builds) or /MD (for release builds) on
the command line. The required LLVM libraries can be listed using the
`llvm-config' script on Unix or MinGW. The dependencies are listed too
in

%LLVMSourceRoot%/cmake/modules/LLVMLibDeps.cmake

bus as this is a bit inconvenient to read, here they are for you:

 -lLLVMX86Disassembler -lLLVMX86AsmParser -lLLVMMCParser
 -lLLVMX86AsmPrinter -lLLVMX86CodeGen -lLLVMSelectionDAG
 -lLLVMAsmPrinter -lLLVMX86Info -lLLVMInterpreter -lLLVMJIT
 -lLLVMExecutionEngine -lLLVMCodeGen -lLLVMScalarOpts -lLLVMInstCombine
 -lLLVMTransformUtils -lLLVMipa -lLLVMAnalysis -lLLVMTarget -lLLVMMC
 -lLLVMCore -lLLVMSupport -lLLVMSystem

Rename -lLIBRARYNAME to \llvm\lib\LIBRARYNAME.lib

HTH.
