Qmake ../ && then make -j12 error

Currently using Stable_V4.3 to build this how can I remove these errors.

Also, while I was working with Stable_V4.0 zero, running the above command gave me the error:
cp: cannot stat ‘/usr/lib/x86_64-linux-gnu/libicudata.so.56’: No such file or directory
make: *** [Makefile:2201: release/QGroundControl] Error 1

Basic linux error, check libicu package

Actually I found the solution to the latest release and I am working with it. But thank you for the response. Hope the solution given helps someone else in the future or maybe me when I incur the similar problem.
