- A config.pro option called search_path: Browse to the location that you want included in the search. I believe it checks for files at the terminus, not recrusively through the whole string. So if you have files at several levels in a multilevel directory stucture, each level needs to be included as a separate search_path statement.
- If you don't want to clutter up config.pro piles of search_path entries, create a file called search.pro that contains all these paths. In config.pro, point to this file with the option search_path_file.
The Fundementals section of the Help file gives a very detailed description of how to go about this. Just search on 'search path'.
