[PATCH] D89356: [cmake] Limit missing external lit warning to be shown once

[Jonas Devlieghere via Phabricator via llvm-commits]

JDevlieghere added inline comments.


================
Comment at: llvm/cmake/modules/AddLLVM.cmake:1661
         return()
-      else()
+      elseif (NOT DEFINED CACHE{LLVM_EXTERNAL_LIT_MISSING_WARNED_ONCE})
         message(WARNING "LLVM_EXTERNAL_LIT set to ${LLVM_EXTERNAL_LIT}, but the path does not exist.")
----------------
This should probably be of type `INTERNAL` which is the same as `CACHE` but without the (G)UI entry.
