Utils header is missing

It doesn't seem to be a TIRPC header:

~/Downloads/libtirpc-1.3.3$ find . -name "utils.h"
~/Downloads/libtirpc-1.3.3$ 

I will try to comment it out, and see which symbols are missing then.

If I had to make a guess it would be one of these:

~/compbiomed/HemePure_tools$ find . -name "utils.h"
./build/palabos/externalLibraries/nanoflann/utils.h
./build/palabos/jlabos/src/plbWrapper/utils/utils.h

The jlabos folder is a Java wrapper of Palabos, so it feels kind of irrelevant here.

Okay, judging by this line in the Makefile which calls Scons:

# Path to inlude directories (other than Palabos)
includePaths = ../palabos/externalLibraries/nanoflann

the utils.h is from nanoflann.

It appears like this header is unused in the voxelizer_MultiInput.cpp variant anyways, so the line could be simply deleted. If needed, e.g. in voxelizer.cpp.nanoflann sourcefile, it may be sensible to replace it with:

#include "nanoflann/utils.h"

to have at-least some provenance documented. The Makefile also needs to be adjusted in this case.
