[feature] Apple platforms - weak frameworks

Conan has convenient way to list frameworks to link against:

self.cpp_info.components["..."].frameworks

Standard way to pass weak framework to linker doesn’t work:

self.cpp_info.components["..."].exelinkflags.append("-weak_framework CoreHaptics")

it’s translated into

-weak_framework  -lCoreHaptics

The only other (and working) way is using -Wl,-weak_framework,CoreHaptics, but it’s rather tedious to type manually.

There can be multiple solutions:

• extend link flags properties to accept some kind of ArgGroup type
• add new weak_frameworks property similar to the existing frameworks
• extend frameworks property to accept some kind of AppleFramework type that would have an is_weak property
• just create a helper function like linked_weak_framework(framework) that would return f"-Wl,-weak_framework,{framework}"

This was briefly discussed in https://github.com/conan-io/conan-center-index/pull/12472#issuecomment-1224500256 and next comment.

@franramirez688 changed SDL’s test package to use CMakeDeps: yes, you’re absolutely right, it works!

I guess the issue can be closed then?

That’s great news! So glad to hear it!

I guess the issue can be closed then?

Yes, I think so.
