title: KDTREE executable in Concorde
body: <p>I'm trying to use the kdtree executable in Concorde but after installation it isn't in the KDTREE directory(or anywhere else I looked).  I've tried rerunning the makefile and reinstalling Concorde but neither helped.  The README and Insallation guide lists a few other executables that are all created when I installed and it seems like kdtree should be created as well. I can't find anything in the documentation or online about how to make it.  Thank you.</p>
