I wrote a function to handle that at some point which I include in
PKGBUILDs on very rare occasions:

function _install_dir {
  _src_dir=$1
  _dest_dir=$2
  _n=${#_src_dir}
  for _file in $(find $_src_dir -type f)
  do
    _dest_file=${_dest_dir}${_file:$_n}
    install -Dm644 $_file $_dest_file
  done
}


Obviously it could be modified to accept a permissions argument as well.
