How does the mod Detect Morrowind assets?

One of the mod requirements was listed as a properly installed version of Morrowind. My question about this is how does the mod locate the morrowind install directory? My copy of Skyrim is through Steam but my copy of morrowind and the expansions I have had for years and are the original Retail CD's Worse the game is installed on a dataDrive Z: because my system uses a small SSD for the system drive and there is not enough room for games in default C:

Since Switching to an SSD I have been forced to become a master of junctions and symbolic links and frankly I end up with tons of these things cross linking all over the place due to mods and software that always assume that the thing they are looking for is installed in program files or steamapps. I just wanted to make sure that this will not become an issue and that the mod will give you the opportunity to manually specify the morrowind install directory n the event that the resources cannot be located
