** Load mu4e
Not all systems that I use have mu/mu4e installed. Either because I cannot really use it at work or because I'm running a native Windows instance or because I didn't completely setup the machine. Therefore I only load/execute the complete mu4e configuration if Emacs can find a =mu= executable.

#+end_src
Not all distributions that I use have a enough up-to-date package of mu/maildir-utils in their repositories. Therefore on some system I compile and install it myself which ends in =/usr/local= instead of just =/usr.= Therefore I have a small function that finds the correct load-path for the mu4e package.

Using the determined load path I now load mu4e itself if the =mu= executable is in path (useful for my work machine where I currently only have Evolution installed but not mu/mu4e) and bind it to a handy keybinding. Since I don't close the parenthesis of the ~use-package~ everything that follows this source code blocks is part of the config section.
