Summary0015469: Xcode projects misuses targets for ALL_BUILD; it should use a scheme instead
DescriptionWhen generating an Xcode project from a CMakeLists.txt with one target, the resultant project contains three targets: the user's target, ALL_BUILD, and ZERO_CHECK. It then makes all targets depend on ZERO_CHECK, and makes ALL_BUILD depend on all other targets.

However, the Xcode documentation specifies "Projects can contain one or more targets, each of which produces one product." - so ALL_BUILD is not the intended use of targets. CMake should instead create an Xcode scheme, which depends on all of the user's Xcode targets.
Steps To Reproduce
Additional InformationDebatably, ZERO_CHECK shouldn't be a target - and ZERO_CHECK's only build phase should instead be a build phase present in every other target. However, you could argue that it does produce a product (ie. the Xcode project itself).

The Xcode documentation quoted in the description is a high-level conceptual description, not an authoritative definition. Not all targets produce a product. Any add_custom_target call in CMake code will generate a target much like ALL_BUILD and ZERO_CHECK containing the specified custom commands.

ZERO_CHECK needs to be a separate target on which all other depend so that its check runs exactly once even in a parallel build.

This is all working as designed and intended.
