Get url of related type content

Hi,

I need help finding the right way to get the url of a related type content.
This is a basic explanation of what I have and need:

CPT FITO. Custom post type fito.
CPT MARCA. Custom post type marca.

For MARCA, we create a field named “relation” and you can choose from a list dropdown to wich FITO is related.

Then, I need to get the link of the FITO related and use it as link of the MARCA list.

This is a fragment of the template where I want to print the link of the related content.

Thanks in advance, I hope someone can help me with this.
