I already did that half ;-)  Here's a simple Makefile I use to build
(almost) all the grammar libraries:

  PARSER_NAME = $(notdir $(abspath $(CURDIR)/..))
  DLL = $(addsuffix .dll,$(addprefix lib,$(PARSER_NAME)))

  CPPSRC := $(filter-out schema.generated.cc,$(filter-out binding.cc,$(wildcard 
  SRC := $(wildcard *.c)
  SRC += $(CPPSRC)
  OBJ := $(addsuffix .o,$(basename $(SRC)))

  CC = gcc
  ifeq (, $(CPPSRC))
          CCLD = gcc
          CCLD = g++
  CFLAGS = -O2 -I.
  CXXFLAGS = -O2 -I.

  all: $(DLL)

  $(DLL): $(OBJ)
          $(CCLD) $(LDFLAGS) -shared $^ $(LDLIBS) -ltree-sitter -o $@

This is for Windows, thus "DLL" and stuff, not .so.  Also, Posix
platforms need -fPIC compiler switch.

There are a couple of grammars that need a slightly more complex
approach, because their repositories produce more than one shared
library.  One notable example is tree-sitter-typescript (which Emacs
