 https://github.com/sakov/nn-c
 > It is not so easy as nn-c depends on Triange which is not a free
 software. Thus it would be necessary to rewrite parts of nn-c to use
 different triangulation code i.e. from v.voronoi module. Feel free to
 provide code to remove Triange dependency from nn-c and then it can be
 integrated into GRASS GIS as nn-c license is compatible with GPL.

 There was also attempt to use CGDAL (see Adam Laza bachelor thesis from
 2015, sorry in Czech only (1)). There were some performance problem with
 CGAL as far as I remember.
