  15 # as http://llvm.org/docs/CMake.html says
  16 # "BUILD_SHARED_LIBS is only recommended for use by LLVM developers. If you want
  17 # to build LLVM as a shared library, you should use the LLVM_BUILD_LLVM_DYLIB option."
  18 # and using fewer shared libraries will make it easier to split up llvm from clang.
  19 # But switching to LLVM_LINK_LLVM_DYLIB currently causes linker errors.
