What NOT TO DO

sudo apt-get install ros-indigo-mavros*

If seeing, UniquePtr does not name a type errors, these are NOT c++11 issues!!
The error is with /opt/ros/indigo/blabla/class_loader.h
Now, what worked FINALLY was sudo apt-get upgrade
No need to change cmake versions (thanks to AirSim you were trying to make running a few days back) and what the hell not.

For installing Qt, use sudo sudo ./qtblabla.run.
for discovering Qt in cmake, set CMAKE_PREFIX_PATH=/opt/Qt/5.8/gcc_64/ or simply $export CMAKE_PREFIX_PATH=/opt/Qt/5.8/gcc_64/
