This has been bugging me for a while. If
Kokkos
has been configured with theThreads
backend, any attempt to reconfigure would fail sinceThreads::Threads
would not be a target anymore.This pull request fixes this bug, by pulling the relevant logic from
FindTPLPthread.cmake
intoFindTPLTHREADS.cmake"
and, thus, making the two independent. The former one is only used forTrilinos
builds anyway (and the latter one is not used forTrilinos
builds).
