Hi Prabhat,
The flags that are inconsistent are not the ones used
for building CMake, but the ones used for building ITK
with respect to the ones used for building Qt,... and
any other library that you are linking together in your
final application.
Did you build Qt on your own ?
Are you using any other libraries besides ITK & Qt ?
Have you manually changed the flags used for configuring
your own application ?
Please let us know,
Thanks
Luis
