Now the run of the application probably mixes versions of Qt5 at load time,
and that leads to subtle binary incompatibilities.

Set the environment variable LD_LIBRARY_PATH before launching the
application, to the paths where the libraries of Qt5 are. That is probably:

export LD_LIBRARY_PATH=/home/pc/src/Qt5.7.0/5.7/gcc_64/lib:/usr/local/lib
