So, I just did some timing on ParaView which is a big project (includes 
VTK).   This is all on windows.  It seems that ninja is the slow one. 
The makefile and VS 10 generator were about the same.  This is a second 
configure, so it does not include the initial try-compile stuff which 
can be slow on windows.

vs 10   real    2m41.935s

ninja    real    3m33.807s

unix makefiles  real    2m43.696s
