-Subject: [PATCH] [opt-viewer] Allow users to set LLVM_HAVE_OPT_VIEWER_MODULES
- manually from the CMake
-
-Check right before setting LLVM_HAVE_OPT_VIEWER_MODULES
-so that if the user specifies the variable on the commandline
-it takes precedence. If not, fall back to the old logic
-
-Upstream-Status: Submitted [https://github.com/llvm/llvm-project/pull/151845]
