LibrePilot/ground/openpilotgcs/src/plugins/coreplugin/fancyactionbar.cpp
stac 7195862d77 build: Move openpilotgcs into its own subdirectory
This will allow us to build a parent project for
qt-creator that sits above both openpilotgcs and
uavobjgenerator so that we can build both projects
at the same time.
