Migrate NAN to NAPI

[sabman]

Migrate the code from the carto branch which used NAN to NAPI.

@2021-12-30 21:03:23 +01:00 working branch: v4.5.0-mapnik-v3.6.2-carto

[sabman]

1. install mapnik

git checkout mapnik-v3.0.24-v3.0.15-carto
PYTHON=python2 ./configure CXX=g++ CC=gcc
# in Makefile change PYTHON=python to PYTHON=python2

2. install node-mapnik

git checkout v4.5.0-mapnik-v3.6.2-carto
make 

Getting the following error right now

Applied fix

std::sort(
  hit.second.begin(), hit.second.end(), [](query_hit const &a, query_hit const &b
) 
  { return a.distance < b.distance; });

Now hitting this compile error:

[artemp]

@sabman you need to upgrade dependencies to later versions, see below -

[sabman]

@artemp updated dependencies (51aa691) but still running into the following error. Odd. Any ideas.
