-``LLVM_ROOT`` should point to the prefix of your llvm installation, so for example,
-if llvm is installed into ``/usr/bin`` and ``/usr/lib64``, then you should pass
-``-DLLVM_ROOT=/usr/``.  Both the ``LLVM_ROOT`` and ``LLVM_EXTERNAL_LIT`` options
-are required to do stand-alone builds for all sub-projects.  Additional required
-options for each sub-project can be found in the table below.

+* The stand-alone build needs to happen in a folder that is not the
+  original folder where LLVMN was built
+  (`$builddir!=$builddir_subproj`).
