[CMake] Running CTest with Xcode build results in Error

[David Cole]

The error shown in your CDash build error output page could be coming
from something that is built within your project as an
ExternalProject.

Do you have any of those?

Have you grepped your source tree for -j yet?

The short of it is that CTest is using xcodebuild (which is correct) but is trying to pass the “-j16” style that normal “MakeFiles” would use. I have looked through our CTest scripts (Which were adapted from VTK’s nightly builds) but I am not seeing anything about that flag being explicitly called out.
