What does it mean when it says (You must select a host application to run a library)

Can someone please help me? What does it mean when it says (You must select a host application to run a library). How would I fix this problem if there even is one? Thanks.

Are you trying to run a library like an executable?

Trying to make an application with it

Basically I'm trying to create a template library and when I try to build and run, that message keeps on coming up.

A library by itself doesn't have an entry point, you need an executable to link it to if you're trying to test things on it.
