[Mlir-commits] [mlir] [MLIR] Reuse the library directory (PR #108579)

[Tulio Magno Quites Machado Filho]

https://github.com/tuliom created https://github.com/llvm/llvm-project/pull/108579

Prefer to get the path to the shared libraries from config.llvm_shlib_dir. Fallback to the previous path only if config.llvm_shlib_dir is not defined.

This ensures the test will pass regardless of the build configuration used downstream.

Subject: [PATCH] [MLIR] Reuse the library directory

Prefer to get the path to the shared libraries from config.llvm_shlib_dir.
Fallback to the previous path only if config.llvm_shlib_dir is not
defined.

This ensures the test will pass regardless of the build configuration
used downstream.
