[Michał Górny via Phabricator via llvm-commits]

mgorny added a comment.

If you don't mind me being busy with other things right now, I've found a simpler reproducer:

  $ cmake -GNinja ../llvm  -DCMAKE_INSTALL_PREFIX=$HOME/llvm-install -DCMAKE_BUILD_TYPE=MinSizeRel -DLLVM_DISTRIBUTION_COMPONENTS=llvm-addr2line
  [...]
  $ ninja install-distribution
  [...]
  [690/691] cd /home/mgorny/llvm-project/llvm-build/tools/llvm-symbo...2line" -P /home/mgorny/llvm-project/llvm-build/cmake_install.cmake
  -- Install configuration: "MinSizeRel"
  CMake Warning (dev) at /usr/share/cmake/Modules/GNUInstallDirs.cmake:241 (message):
    Unable to determine default CMAKE_INSTALL_LIBDIR directory because no
    target architecture is known.  Please enable at least one language before
    including GNUInstallDirs.
