Setting the path for Haskell libraries
The Haskell interpreter needs to know where to find non-standard Haskell libraries.

To set the path for Haskell libraries go to Program -> Options.

Select the Paths tab.

Click the button next to the Directory of Haskell libraries field.

Navigate to the directory where your libraries are storred.

Click Save. The Path is saved to the settings file. Also HEAT's intermediate files will be saved in this directory.
