I tried to install ginkgo, using the same configuration given in newellVariables.sh, i.e.,
ginkgo@glu_experimental%gcc@8.3.1+cuda~develtools~full_optimizations~hwloc~ipo~oneapi+openmp~rocm+shared build_type=Release cuda_arch=70 arch=linux-rhel7-power9le

but then I got the following error:
[+] /usr/tce/packages/cuda/cuda-11.7.0 (external cuda-11.7.0-uokrglpk6zzlvaq2gpfrfgmgtdikqize) ==> Error: Can't extrapolate a URL for version glu_experimental because package ginkgo defines no URLs

Maybe a customized repository needs to be provided.
