closes: #7493

Changelog: Bugfix: correctly set CMAKE_OSX_SYSROOT and CMAKE_OSX_ARCHITECTURES.
Docs: omit

what exactly has been fixed?

  • custom setting (e.g. arch=ios_far) will not result in -DCMAKE_OSX_ARCHITECTURES="None"

  • return correct SDK root (e.g. iPhoneOS.platform) for custom settings (e.g. os=iOS and arch=ios_fat)

  • it's redundant to invoke xcrun if environment variable SDKROOT was set - CMake will use it anyway

  • don't try to set CMAKE_OSX_ARCHITECTURES/CMAKE_OSX_SYSROOT if toolchain file is used (see comment as well)

  • Refer to the issue that supports this Pull Request.

  • If the issue has missing info, explain the purpose/use case/pain/need that covers this Pull Request.

  • I've read the Contributing guide.

  • I've followed the PEP8 style guides for Python code.

  • I've opened another PR in the Conan docs repo to the develop branch, documenting this one.

Note: By default this PR will skip the slower tests and will use a limited set of python versions. Check here how to increase the testing level by writing some tags in the current PR body text.

This was assigned to 1.28.1, but was incorrectly merged to develop instead of release/1.28.

@czoido will port it to release/1.28. Thanks!
