On Linux there is a way to get the executable path, see 
https://github.com/DanielGibson/Snippets/blob/master/DG_misc.h#L239 
(after that you only need to remove everything right of the last slash 
to remove the executable name itself from the path).

On OSX things can be contained in .app bundles, but I'm not very 
familiar with that.
