I'm not very familiar with Xcode-specific things like xctest binaries.
Please briefly explain their purpose, how they work, and how developers
might use them.  How should they be treated on non-Apple platforms?

So far I've only xctest in Modules/CMakeDetermineCompilerId.cmake
for the compiler identification project for iPhone platforms:

Why is it a MODULE?

These two could be implied by XCTEST as needed.

>   XCTEST TRUE
>   TEST_HOST CocoaExample

Please explain what each of these does.

Thanks,
