Previous changes from v4.0.0

    • 👌 Improved CMake packaging it is now possible to:
      • Install function2 properly
      • Include a function2 subdirectory as subproject
    • The minimum CMake version was raised to 3.11 because of issues with imported interface
      targets on lower versions.

    • Interface breaking change: The capacity is now an integral_type like type rather than
      specifying the size directly, this makes it possible to also specify the alignment and
      👍 it works better with capacities that shall hold a forward declared object which is defined later.

      struct my_capacity { static constexpr std::size_t capacity = sizeof(my_type); static constexpr std::size_t alignment = alignof(my_type); };
