This is what I have on my x86 JIT compiler:

set(REQ_LLVM_LIBRARIES
  LLVMX86CodeGen
  LLVMX86Info
  LLVMSelectionDAG
  LLVMAsmPrinter
  LLVMInterpreter
  LLVMJIT
  LLVMExecutionEngine
  LLVMCodeGen
  LLVMipo
  LLVMInstrumentation
  LLVMScalarOpts
  LLVMInstCombine
  LLVMTransformUtils
  LLVMipa
  LLVMAnalysis
  LLVMTarget
  LLVMMC
  LLVMBitWriter
  LLVMCore
  LLVMSupport
  LLVMSystem
  )

You can remove LLVMBitWriter if you don't plan to output LLVM bitcode.
