I myself use the following BiBtex entry (please adapt to the version you use):

@Manual{Granlund12,
  title = 	 "{GNU MP}: {T}he {GNU} {M}ultiple {P}recision
		  {A}rithmetic {L}ibrary",
  author = "Torbjörn Granlund and {the GMP development team}",
  edition = 	 "5.0.5",
  year = 	 2012,
  note = "\url{http://gmplib.org/}"
}

Citing software tools such as GMP with full bibliographic entries is better,
since it increases their visibility in scientific documents.
