   3 Subject: [PATCH] Fix cmake configure for shared LLVM libraries
   4
   5 Gentoo builds LLVM into a combined shared library. The CMake
   6 configuration shipped with LLVM is evidently broken in this case, see
   7
   8   https://github.com/llvm/llvm-project/issues/34593
   9   https://bugs.gentoo.org/745915
  10
  11 We work around this issue by simply linking against the monolithic
  12 "LLVM" target.
