This looks like a try-compile is failing for some reason.   Can you 
check your CMakeCache.txt for HAVE_STRERROR and also the CMakeError.log 
and CMakeOutput.log for both the makefile and the Xcode project.  I am 
guessing they will be different.

I just checked the CMakeList files for vtknetcfd and I think there maybe 
a bug with HAVE_STRERROR.   vtknetcfd is depending on vtklibxml2 to do 
the try-compile for this.   It should have its own check.
