+1. **Compiler Options**: If you specify paths using the compiler options, these will override the correponding paths set via environment variables. 
----------------
I think it would be easier to understand by explicitly calling out the order of precedence:

- For HIP path:
      - --hip-path option
      - HIP_PATH env var
      - --rocm-path option
     - ROCM_PATH env var
     - default automatic detection


-- For device lib:
      - --hip-device-lib-path option
      - HIP_DEVICE_LIB_PATH env var
      - --rocm-path option
      -  ROCM_PATH env var
      - default automatic detection
