unexpected test_o3dgc build issue

When building with:

mkdir build
cd build
cmake ../src
make

the build of the test application falls with the following, the issue is the signature of IVec3Cmp operator() needs to be const, as in
bool operator()(const Vec3<unsigned long> a,const Vec3<unsigned long> b) const
