Herwig7_i: Compile BB4LH7 shared library only on x86_64 (!72968) · Merge requests · atlas / athena

Katharina Voss requested to merge katharin/athena:HerwigBB4L_PwhgSO into main Jul 11, 2024

Compile the shared library powhegHerwigBB4L introduced in !72582 (merged) only if CMAKE_HOST_SYSTEM_PROCESSOR is x86_64, since including powhegSOforHerwig leads to a failed compilation on aarch64-el9-gcc13-opt nightly, see this log as reported by @tsulaia. This change was kindly suggested by @averbyts, since POWHEG on ARM is WIP.
