+Subject: [PATCH 09/10] cmake: Use system llvm-lit when lit.py does not exist
+ in srcdir
+
+Modify the add_lit_target function to use lit.py from LLVM_MAIN_SRC_DIR
+only when one does exist there, and otherwise fall back to looking for
+system install of llvm-lit. This is based on a similar conditional in
+clang's CMakeLists.txt, and makes it possible to run clang's tests when
+built separately from LLVM with no access to the original sources.
