environment variable before launching Julia. For example, if ROCm is installed
in your Linux system root (e.g. on Fedora), set `ROCM_PATH=/usr/lib64/rocm/gfx11` or
`ROCM_PATH=/usr/lib64/rocm/gfx1103`, depending on your GPU's architecture. You
can query the architecture using the `amdgpu-arch` command. The `AMDGPU.versioninfo()`
function prints the paths of any libraries found.

Depending on your GPU model and the functionality you want to use, you may have
to force the GPU architecture by setting the `HSA_OVERRIDE_GFX_VERSION`
variable to a compatible version.
