hipSYCL Compilation Error

[calgray]

When compiling with hipSYCL using the README.md command cmake .. -DhipSYCL_DIR=/opt/hipSYCL/CUDA/lib/cmake/hipSYCL -DSYCL_COMPILER=hipsycl I get the attached compiler error multiple times. My guess is a release version of hipSYCL such as v0.9.1 is needed rather than the repo default branch but I'm guessing that a breaking version change since the initial hipSYCL support is the issue.

Building master on Arch Linux with packages: computecpp: 2.3.0-1 hipsycl-cuda-git: r1419.72b201e-1 gcc: 11.1.0-1

Compiler Error:
