#	This file is NOT working as expected. So expect errors while building!

#	This file is a modified version of the original CMakeLists.txt file 
#	for the app RegionGrowingSegmentation
#	The original file can be found in ITKApps/RegionGrowingSegmentation

#	The aim is to build a simplified version of the same app without a
#	GUI. Hence FLTK is used only for displaying the images. The program
#	communicates with the user through a CLI
