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