[hariharan-devarajan]

We make the following dynamic based on env.

• HWLOC
• HIP
• MPI

Pull Request Overview

This PR refactors build system options to make feature detection dynamic based on the environment instead of requiring explicit user configuration. The changes convert several hardcoded CMake options (HWLOC, HIP, and MPI) from manual opt-in flags to automatic detection that queries the system for available libraries.

Key Changes:

• Removed manual CMake options for HWLOC, HIP, and MPI support
• Implemented automatic find_package() detection with QUIET flag for graceful fallback
• Changed error handling from FATAL_ERROR to informational STATUS messages when optional dependencies are missing

Can you add a high level knob to enable detection based on user's request? The knob would be disabled by default

[hariharan-devarajan]

DONE

Ok I have added a variable for automatic detection. That is off by default but if on, would ignore if user wanted to enable or disable feature.

@amarathe84 Can you check the PR

[amarathe84]

Minor nit: should this be '--enable-dynamic-detection'? Existing option name suggests slightly different interpretation

[hariharan-devarajan]

Done.

Changes look good.
