Adding libpoint-to-point to libapplications' cmake dependence leads to libpoint-to-point missing SimpleSeqTsHeader, which is in libapplications. This results in cyclic-dependence

Research direction
Start by running ./scripts/build.sh -c ns3 on macOS and inspect the CMake dependency declarations for libapplications and libpoint-to-point. Trace the missing RdmaDriver symbols from rdma-client.cc and verify where SimpleSeqTsHeader is defined. Done means the ns3 build links successfully on arm64 without introducing a cyclic library dependency.
