How to link a git repo to another git repo for build artifact (like .lvlibp) dependencies?

[Ajay_MV]

I have a git repo that releases pack library (*.lvlibp) now and then.

A new project now depends on a packed library from the above-mentioned project and this new project needs the newly released packed library.

How could you link such released binaries from one repo to another repo in git?

I used to use SVN External previously to link such released library versions and SVN External worked like charm.  For Git, all I could find is that I can link the whole repo as a submodule in git, but not the specific folder.  However, I want to link only the build folder to a new project.  

Thanks,

Ajay.
