This has been fixed/broken sooooo  many times....  No one reports the 
errors back.   It should be pretty easy to fix, just add a few 
add_dependencies statements.  In fact, Luis you and I looked at this 
about 6 months ago, and there was an ifdef windows thing.  Because the 
windows build would not work at all since VS always does parallel these 
days.   So, I would first look for add_dependencies  calls in the ITK 
cmake lists files.  If they are conditional on WIN32 get rid of that and 
always do it.   If that is not the problem, I would need a list of the 
errors in the parallel build.

After that we need a dashboard that does a parallel build of ITK with 
wrapping so this does not break again, and again, and again.... :)
