[OS X TeX] Style file placement

[Themis Matsoukas via MacOSX-TeX]

I am using the mdpi style files (https://www.mdpi.com/authors/latex) which are contained in a folder called "Definitions". The folder contains a bunch of files, including the class file mdpi.cls, the bst file, as well as some eps files that add journal-specific graphics to the manuscript. 

If I place the folder Definitions in the same folder as the manuscript, everything works fine.

If I place the folder Definitions in my personal folder /~/Library/texmf/tex/latex/TM Inputs, the document typesets but does not find the eps files or the bst file. Looking into the style file, all paths are hardwired as Definitions/filexyz.

Is there an easy fix? I'd rather not have to copy Definitions in every folder.
