Guess I found a bug here and already filed it:
- Created custom profile,
- added https://www.drupal.org/project/mmenu dependency (which then is placed under
- Added MMenu libraries (jquery.mmenu, hammer.js, jquery.hammer),
- activated everything but then Drupal looks for the wrong library paths under
libraries_get_path('mmenu') returns correct path
drupal_get_profile() returns correct profile.
Drupal seems to only take the paths defined in
mmenu.libraries.yml into account. Changing them makes everything work as desired. So, I'm asking myself now: Is there any possibility to override the paths defined in
mmenu.libraries.yml from a custom module?
