No central header in ITK lists all the modules because the set
that is loaded is not known until the application calls the
find_package(ITK) command.  It can specify a subset of modules.

You should configure it into a local header.  The line

 #cmakedefine ITKReview_LOADED

should work with configure_file as long as it occurs after the
find_package(ITK) call.  Local testing works for me.
