ROMIO fails to build if level_zero is installed

[acgoldma]

Thank you for taking the time to submit an issue!

Background information

What version of Open MPI are you using? (e.g., v3.0.5, v4.0.2, git branch name and hash, etc.)

#10224

Describe how Open MPI was installed (e.g., from a source/distribution tarball, from a git clone, from an operating system distribution package, etc.)

I was attempting to build OMPI rpm

If you are building/installing from a git clone, please copy-n-paste the output from git submodule status.

#10224
openpmix @ 6692c28
prrte @ 7ae2c08

Please describe the system on which you are running

• Operating system/version: RHEL 8.4
• Computer hardware: Intel E5-2699 v3
• Network type: N/A

Details of the problem

Looks like romio341 detects Level-Zero on my system and causes issues.

Looks like it is not using the correct API?

@acgoldma Sorry for the 2-year wait. Does this problem still happen with latest romio and ompi 5.0.3?

did not see an issue recently.
