[CMake] Xcode Archiving on iOS and OSX

[Jamie Hales]

I've got a little further with this over the weekend. By doing a "Product->Build For->Archiving" before "Product->Archive" seems to build the xcode archives into the correct location, I'm not sure why this is the case. Regardless, that allows it to link correctly. The problem then is it by default creates a 0 byte xcarchive file. This is apparently because the default install path is empty, which Xcode doesn't like. Skip install is also set on the project target by default, which is incorrect. 

You can solve this by setting the following properties on the application target.

set_target_properties(${projectname} PROPERTIES
XCODE_ATTRIBUTE_INSTALL_PATH "$(LOCAL_APPS_DIR)"
XCODE_ATTRIBUTE_SKIP_INSTALL "No"
)


This seemingly allows the creation of a valid archive, so it's usable, there's just the extra step of having to build before archiving. If anyone has any suggestions on how to solve that final hurdle it would be greatly appreciated!

So far it's going well, I have the OSX and iOS targets up and running correctly when running directly on the device, but I'm having issues when archiving.
