"'lua.h' file not found" on macOS 15.1 (ARM64)

[bun4byte]

I'm including Sol2 in my project using FetchContent in CMake. I have Lua installed on my system, both through Homebrew (brew install lua) and from source code (make install in a copy of the Lua source). On my system, a copy of lua.h is located in /user/local/include next to lua.hpp, luaconf.h, and lualib.h. /usr/local/include is a standard include path on my system that most build systems can recognise.

No matter what I do, however, I always get the same build error. How do I fix it?

This is my CMakeLists file for reference:

cmake_minimum_required(VERSION 3.5.0)
project(cast)

set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED True)
set(CMAKE_CXX_FLAGS "-Wall -Wextra -O3")

include(FetchContent)

find_package(libzip REQUIRED)

FetchContent_Declare(
	sol2
	GIT_REPOSITORY https://github.com/ThePhD/sol2.git
	GIT_TAG main
)
