HIP Runtime Linker Errors about umpire HOT 6 CLOSED

The fix has been merged into develop and I have validated the patch myself. Thanks for the help!

The hip_runtime target comes from BLT. When you build a HIP-enabled Umpire it is required to be linked to the HIP runtime library, which is most easily done by linking with hipcc. The target handles this.

How do you support HIP compilation in your application?

Perhaps I'm just misusing the library. According to this issue in ROCm repo, we set C++ compiler to hip clang and link against hip::device for device code, as discussed on this ROCm documentation page. Do you see anything immediately wrong with this, and is there additional documentation for using Umpire with hip?

from umpire.

For additional context:

• The error occurs in the link step, the sources with RAJA kernels using HIP policies compile fine.
• The final linked targets also link to cmake target hip::device, and are confirmed to use --hip-link

We ran into this issue with RAJA - would you like me to raise an issue on that repo as well? After removing the hip_runtime targets manually our entire stack built and ran successfully.

I'm hopeful that #541 will help - if you would like to try and build and install that branch and see if the issue goes away that would be super helpful. I can than make the same change to RAJA.
