In order to make tests for plannerShared, some qt-models must
be linked, and due to the fact that commands are currently not
available for mobile (which also makes the tests) and #ifdef must
be added.
The test version of diveplannermodel will be specially compiled in
(SUBSURFACE_TESTING set) in the tests directory.
