<div dir="ltr"><div><div>In your executable project (which contains the application specific code, namely, an ITK application), you can "super build" ITK as a third party library. You could specify the corresponding module cmake variable (Module_<your remote module name> = ON ) to include the remote module when building ITK. You can refer to Slicer on this.<br>
</div></div><div><br></div><div>Or if the project size is not very big, you can also put in your executable code together in your remote module. They serve as great examples. You can refer to LesionSizingToolkit[1],which is an ITK remote module. But yes, you need to build your remote module in the process of building ITK. </div>
