Building traccc against non-installed ROCm version

With main I have now managed to build some of ACTS + traccc_alpaka_hip against ROCm 7.13.0 + clang 22 on a machine with an AMD GPU + ROCm installed in the standard `/opt/rocm`
Recipe:
```sh
asetup main,latest,Athena,clang
source /cvmfs/sft.cern.ch/lcg/contrib/rocm/7.13.0/x86_64-el9/setup.sh
export HIPCXX=`which amdclang++`
cmake ../acts/Traccc \

```
It's very annoying that we have to set CMAKE_PREFIX_PATH and 8 additional paths. Unclear to me where this is coming from: the assumption that rocm is in `/opt/rocm` is very strong.

After this step, it fails with an internal compiler error:
```
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
