Get a list of swift's system libraries on macOS for different systems in CMake3.28

Preface:

The C++ project links to a dynamic library that uses Swift, but CMake does not see this and does not put the necessary libs and i get many errors

ld: warning: Could not find or use auto-linked framework 'libswiftCompatibility*' not found
*link errors*

What did I do:

The first option to solve the problem is to add an empty .swift file to the sources, which will trigger xcodebuild and put the libs itself

The second option I took it from Apple repository, but it only works for macOS. I need the same functionality for iOS.

To get a list of libs for both macOS and iOS, just call the command

swiftc -sdk /path/to/sdk/<platform>.sdk -target <triple> -print-target-info where <triple> is an arm64-apple-macos17.2, for example, and for different platforms, it is obviously different

In CMake, I wrote such an implementation

execute_process(
    COMMAND xcrun --show-sdk-path --sdk ${CMAKE_OSX_SYSROOT}
    OUTPUT_VARIABLE SDK_PATH
    OUTPUT_STRIP_TRAILING_WHITESPACE)
execute_process(
    COMMAND xcrun --show-sdk-platform-version --sdk
            ${CMAKE_OSX_SYSROOT}
    OUTPUT_VARIABLE SDK_VERSION
    OUTPUT_STRIP_TRAILING_WHITESPACE)
if(CMAKE_SYSTEM_NAME STREQUAL "Darwin")
    set(TARGET_PLATFORM "macos")
elseif(CMAKE_SYSTEM_NAME STREQUAL "iOS")
    set(TARGET_PLATFORM "ios")
endif()
set(SDK_FLAGS
    "-sdk"
    "${SDK_PATH}"
    "-target"
    "${CMAKE_OSX_ARCHITECTURES}-apple-${TARGET_PLATFORM}${SDK_VERSION}"
)

And the question is this:

Is there some more beautiful/correct way to get a list of libs (in this case, the way to get <triple> bothers me, it seems to me at one point something will fall off) or maybe in the new CMake there is a way to link all libs without problems?
