Summary

Searching for curand explicitly (required by default by AMReX) makes HPE/Cray builds more robust when we build w/o compiler wrappers, e.g., if files are distributed in a non-standard layout.

Compile error on Perlmutter with g++ and nvcc as compilers was:

Checklist

The proposed changes:

• fix a bug or incorrect behavior in AMReX
• add new capabilities to AMReX
• changes answers in the test suite to more than roundoff level
• are likely to significantly affect the results of downstream AMReX users
• include documentation in the code and/or rst files, if appropriate
