* Fix cmake detection on pthread_affinity test on FreeBSD In FreeBSD, non posix thread functions locate in the pthread_np.h. We check the platform and include the correct header. Also, pthread related features in some platforms require link to special library. We append Threads target to BENCHMARK_CXX_LIBRARIES so that it can be added by cxx_feature_check. * fixup!
