SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***


STEPS TO REPRODUCE
1. Build and install snap
2. launch snap
3. Works but without plugins or default image textiles

OBSERVED RESULT
I have tried setting 
runtime:
    MARBLE_PLUGIN_PATH: $SNAP/usr/lib/$CRAFT_ARCH_TRIPLET/marble/plugins
    MARBLE_DATA_PATH: $SNAP/usr/share/marble/data
buildtime:
        - "-DMARBLE_PLUGIN_INSTALL_PATH=/usr/lib/$CRAFT_ARCH_TRIPLET/qt5/plugins/"
        - "-DMARBLE_DATA_INSTALL_PATH=/usr/share/marble/data"

And every variation I could find on the interwebs to no avail. Marble can't find its plugins.
