  description: |
    This feedstock builds the hwloc library in the `libhwloc` conda package. Different variants of the package are built:
    * `default` in the build string: Without CUDA or ROCM support, installed by default. Install specifically this version with `conda install libhwloc=*=*default*`.
    * `cuda` in the build string: With CUDA support. Install specifically this version with  `conda install libhwloc=*=*cuda*`
    * `rocm` in the build string: With ROCM support. Install specifically this version with  `conda install libhwloc=*=*rocm*`
