> Do you think this is best done as a module like `FindGTest` and its CMake API or something built-in for CMake (i.e., C++ code)? We do now have an experimental feature gate mechanism to aid in deploying this without committing to a stable interface if that would help get more feedback.

Definitely no need to write new C++ code in this case! As noted [here](https://discourse.cmake.org/t/the-testee-of-xctest-add-bundle/10120) I view this mostly as a modernization of the existing `FindXCTest` so I think `FindXCTest` (or `FindSwiftXCTest` if my code can’t be made to work with Objective-C on macOS—I haven’t tried that) would be appropriate.

The one complication I see is that support for non-macOS platforms involves [building](https://github.com/hylo-lang/SwiftCMakeXCTesting/blob/12e64e0d1c7a422f01e4601eadefa743811e45f5/CMakeLists.txt#L24-L40) and running a code generator [written in Swift](https://github.com/hylo-lang/SwiftCMakeXCTesting/blob/main/Sources/GenerateXCTestMain.swift). I don’t know if there’s any precedent for including something like that in CMake… but ideally the whole thing belongs there.
