[CMake] Running CTest with Xcode build results in Error

[David Cole]

Are you using Eclipse or Kate?

Did you do a grep -E "\-j" on all of the files included by the script
that drives the build? (And in your source tree?)

The only -j possibilities that look likely in CMake itself are shown
in the git grep results from a CMake checkout:

$ git grep -E "\-j"

Modules/CMakeFindEclipseCDT4.cmake:# Try to find out how many CPUs we
have and set the -j
Modules/CMakeFindEclipseCDT4.cmake:# Only set -j if we are under UNIX
and if the make-tool
Modules/CMakeFindEclipseCDT4.cmake:
set(_CMAKE_ECLIPSE_INITIAL_MAKE_ARGS "-j${_CMAKE_ECLI
Modules/CMakeFindEclipseCDT4.cmake:set(CMAKE_ECLIPSE_MAKE_ARGUMENTS
"${_CMAKE_ECLIPSE_INIT
Modules/CMakeFindKate.cmake:# Try to find out how many CPUs we have
and set the -j argumen
Modules/CMakeFindKate.cmake:# Only set -j if we are under UNIX and if
the make-tool used a
Modules/CMakeFindKate.cmake:  set(_CMAKE_KATE_INITIAL_MAKE_ARGS
"-j${_CMAKE_KATE_PROCESSOR
Modules/CMakeFindKate.cmake:set(CMAKE_KATE_MAKE_ARGUMENTS
"${_CMAKE_KATE_INITIAL_MAKE_ARGS

And it looks like those try to restrict it to a "make" tool, so they
shouldn't be using it in the case of xcodebuild...

Mystery. We're missing something.

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.
