-Subject: [PATCH] [AMD] Search HIP_PATH, hipconfig, and ROCM_PATH for
- libamdhip64
-
-Search for libamdhip64 from HIP_PATH env var, hipconfig --path output,
-and ROCM_PATH before looking in system-wide ldconfig or /opt/rocm.
-
-The system-wide ROCm path isn't guaranteed to be where the ROCm
-install we're building against is located, so follow typical ROCm
-lib behavior and look under env paths first.
-
-This is especially important for non-FHS distros like NixOS
-where /opt/rocm never exists, but may be useful in more
-typical distros if multiple ROCm installs are present
-to ensure the right libamdhip64.so is picked up.
