Per discussion: https://discuss.tvm.ai/t/latest-tvm-failed-to-build-on-mac-osx-with-llvm10/6993
The issue is found to be caused by LLVM's CMake returning nothing:
llvm_map_components_to_libnames(LLVM_LIBS "all")
. To fix this, this patch checks if "LLVM_LIBS" is empty, and if so, it falls back to use "llvm-config" to configure the project.Could you confirm on your side? Thanks! @Lyken17 @kparzysz-quic @antinucleon
