[CMake] [EXTERNAL]: CMake and Code Signing in XCode 8 for iOS projects

[Parag Chandra]

Hi Frank,

I got curious about this myself, and it looks like the checkbox alters the following in the .pbxproj:

				TargetAttributes = {
					2BA1B86D1DE33AA300073B96 = {
						CreatedOnToolsVersion = 8.1;
						ProvisioningStyle = Manual;
					};
				};


With it  checked, “ProvisioningStyle = Automatic”. To the best of my knowledge, XCODE_ATTRIBUTE_* can only be used for items that show up with a corresponding “Declaration” field when viewed in Xcode’s Quick Help pane, e.g. “ARCHS” can be set via XCODE_ATTRIBUTE_ARCHS.

I had a similar problem targeting NaCl with the Visual Studio generator – there was a property in the .vcxproj file that I couldn’t access directly from CMake. I ended up writing a simple Python script to massage the generated vcxproj in order to give me the desired end result. Not a great solution, but it’s worked out pretty well for me because in practice I don’t run CMake directly on the cmd line. I drive it from a Gradle script which feeds it all the necessary cmd line args I need, so I just tacked on this bit of Python to the end of my Gradle script.

Hope this helps.

    Hi all,
    
    CMake was able to configure automatic code signing for XCode <=7 and iOS 
    projects with a target property setting like
    
    set_target_properties(app PROPERTIES XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY 
    "PROPER IDENTIFIER")
    
    XCode 8 changed the signing process. It now is required that the option 
    "Automatically manage signing" in the project settings "General tab -> 
    Signing" is checked. If I check this options manually for a cmake 
    generated project, signing works well. But I did not find a way to 
    enable this option from the cmake project by default. Can this be done 
    for cmake (>=3.7.0)?
    
    Thanks for any help,
    Frank
