According to the man page, it's part of the standard libc:

CAP_RIGHTS_INIT(3)     FreeBSD Library Functions Manual     CAP_RIGHTS_INIT(3)

NAME
     cap_rights_init, cap_rights_set, cap_rights_clear, cap_rights_is_set,
     cap_rights_is_valid, cap_rights_merge, cap_rights_remove,
     cap_rights_contains -- manage cap_rights_t structure

LIBRARY
     Standard C Library (libc, -lc)
