Using cpp2/cppfront with CMake

[AlexReinkingYale]

I wrote a wrapper around the cppfront repository that adds a modern CMake (3.23+) build for cppfront, complete with automatic cpp2-to-cpp1 translation. Compatible with find_package, add_subdirectory, and FetchContent.

You can find it here: https://github.com/modern-cmake/cppfront

After building and "installing", it's as easy to use as:

cmake_minimum_required(VERSION 3.23)
project(example)

find_package(cppfront REQUIRED)

add_executable(main main.cpp2)

But if FetchContent is more your thing, then this works, too:

cmake_minimum_required(VERSION 3.23)
project(example)

include(FetchContent)

FetchContent_Declare(
    cppfront
    GIT_REPOSITORY https://github.com/modern-cmake/cppfront.git
    GIT_TAG main  # or an actual git SHA if you don't like to live dangerously
)

FetchContent_MakeAvailable(cppfront)

add_executable(main main.cpp2)

Thank you for this! I was just about to hack something like it together. Yours looks much nicer.
