# NOTE: Just replace all three occurences of `tree-sitter-c` to whatever language grammar you are compiling. Nothing else needs changed.
# Then just run `cmake -B bld` and `cmake --build bld` to get a shared object file that can be installed according to https://tree-sitter.github.io/tree-sitter/syntax-highlighting#paths .

If you get errors that look like this

you will have to add src/scanner.c or src/scanner.cc to the list of sources in add_library

cmake_minimum_required(VERSION 3.14)
project(tree-sitter-cpp)

add_library(
  tree-sitter-cpp
  SHARED
  src/parser.c
  src/scanner.cc
)

target_include_directories(
  tree-sitter-cpp
  PUBLIC
  src
)

This is needed because some parsers write their own "external scanner" implementation that the tree sitter parser then uses.
