Firmware upload on PX4FMU using Qt Creator issue (Linux)

Hello, i’m new here, and i want to make some custom changes in PX4 code (adding external IMU sensor). I want to try changes on PX4 board.
The problem is that i did not find a working example for setting up my IDE. I have tried everything i found on this site and other forums, but nothing works.
I noticed that after running cmake command in route directory, ‘make px4fmu-v2_default’ does not work.

Thank you, Igor.
