[CMake] Adding Core Data model files to a CMake generated Xcode project

[James Munro]

Just to quickly update on this issue:

I have made some progress, and the file is now included in the generated
project:

# Core Data model.
set (data_model Resources/Data/${NAME}.xcdatamodeld)
set (APP_TYPE MACOSX_BUNDLE)
add_executable (${NAME}
    ${APP_TYPE}
    ${headers}
    ${sources}
    ${resources}
    ${data_model}
    ${PROJECT_SOURCE_DIR}/Source/${NAME}-Prefix.pch
)
set_target_properties (${NAME} PROPERTIES RESOURCE ${resources}
${data_model})

There are still a couple of issues: Xcode doesn't technically recognise it
as the correct filetype, so you don't get to use the built in editor for
this file type. Additionally, it is not added to the project's build
target, I can't work out why. Adding it manually by ticking the relevant
target checkbox causes it to be included and compiled/handled correctly
when running the project.

So there's 2 remaining issues:

1. Xcode doesn't recognise the file type correctly.
2. It is not added to the build target.

I suspect that the Xcode project generator code is simply not aware of this
type of file.

Kind regards
