This provides helpful cmake interfaces:

  • Fypp_target_sources equivalent to target_sources. This is the main interface that should be used
  • Fypp_add_library = add_library + Fypp_target_sources
  • Fypp_add_executable = add_executable + Fypp_target_sources

The project is structured such that users can include fypp via FetchContent, e.g.:

cmake_minimum_required(VERSION 3.11)
project(test_fypp LANGUAGES Fortran)

FetchContent_Declare(
  Fypp
  # Pointing to my fork until it is merged
  GIT_REPOSITORY https://github.com/LecrisUT/fypp
  GIT_TAG cmake/cmake
)
FetchContent_MakeAvailable(Fypp)

Fypp_add_executable(test_fypp main.fypp)

Depends on #27, #29

- For backwards compatibility, -D will continue to be interpreted as Python expression until 4.0
- Introduced a temporary variable -d/--define-value-type to switch to the proper interpretation when set to `str`

Going to wait for #27 and #29 because it is better to handle the call with python -m fypp
