+  # We set LLVM_MAIN_INCLUDE_DIR so that it gets included in TableGen flags.
+  set(LLVM_MAIN_INCLUDE_DIR "${LLVM_BUILD_MAIN_INCLUDE_DIR}" CACHE PATH "Path to LLVM's source include dir")
+  # We set LLVM_CMAKE_PATH so that GetSVN.cmake is found correctly when building SVNVersion.inc

The old code used the equivalent of `LLVM_INCLUDE_DIR` (i.e. the include dir of *installed* LLVM) and I think the new code should use the same. Given how long the old code was there, I suppose there shouldn't be any use case broken by using that directory.
Please note that it works well when running against a LLVM/Clang build-tree, which is a very common (but indeed not the only) use case this code should support.
