> We need LLVM headers to use Gandiva. (Some public Gandiva headers use LLVM headers.) If we build PyArrow with Gandiva support, we need LLVM as a build-time dependency. Yes, and LLVM + its headers are during build time from the standard location in the `$PREFIX`. CMake is easily able to find it based on that, but the custom (AFAICT) `findLLVMAlt` has it's own checks that fail to find it now (or need something more; is `LLVM_DIR` suppqosed to be `$PREFIX/lib` or `$PREFIX/include/llvm` or something else?) -- This is an automated message from the Apache Git Service.
