[ncl-install] Cannot build without triangle.h

[David Brown]

Hi Orion,

You are right. There is a bug in our conditional code. You can fix it  
by editing
CnTriMeshRenderer.c in <yourpath>ncarg/ni/src/lib/hlu with this diff:

RCS file: /fs/scd/home1/ncargd/CVS/ncarg/ni/src/lib/hlu/ 
CnTriMeshRenderer.c,v
retrieving revision 1.9
diff -r1.9 CnTriMeshRenderer.c
32a33
 > #ifdef BuildTRIANGLE
34a36
 > #endif

Essentially that just puts
#ifdef BuildTRIANGLE

#endif

around the lines

#define REAL double
#include <ncarg/hlu/triangle.h>

Thanks for finding this.
