How to add a qt project as widget to another qt project?

[Sicong]

I'm building a virtual smart car UI. I want to add a map I built from ArcGIS Qt SDK as a widget to my master qt project... Is there any way to do that? or is there a better way to make a navigation map like the ones in the car?

Hi and welcome to devnet,

You can make that part a library and use the SUBDIRS template to build a project that can have several sub-projects.
