[Insight-developers] No longer building XCode

[Bradley Lowekamp]

Hello,

I modified the CTest script to not add any additional warning flags, so the FLAGS are just empty now. I fired it off at about 3pm and it's still going, it's not producing a heck of a lot of warning, but it is up to 9400K of output. This appears to indicate that it's not related to the amount of warninga produced, but doesn't rule out an increase in the amount of time spent parsing the output. 

Also looking at the graph linked below, I don't see a correlation with the number of warning and the increase time to build ITK.

If it is spending a lot of time parsing the output, I should check to ensure that my cmake was built in release mode. That will be the experiment for tomorrow. I would be surprised if lack of cmake optimization would cause 3X in crease in build time. I still think the modularization may not be playing well with XCode.
