I did search on packages.ubuntu.com.
According to it you need the following packages:
for compilation:
sudo apt-get install qtbase5-dev libgl1-mesa-devat run time:
sudo apt-get install libqt5widgets5 libqt5gui5 libqt5core5a libgl1

well, I have found the libs, I have copied libQt5Widgets.so and others from /usr/lib/x86_64-linux-gnu to /usr/lib but the errors still appear.

You should not copy anything from anywhere to the places maintained by package manager (APT)!!! With such actions you can trash and mess your system!!! If you want to copy some lib, copy it to the folder folder with your compiled binary.

I have solved it by adding these entries in the projects ".pro" file and then generating again the Makefile with qmake.
The entries are:
QMAKE_CFLAGS += -no-pie
QMAKE_CXXFLAGS += -no-pie
QMAKE_LFLAGS += -no-pie -fPIC
LIBS += -llua -ldl -L/usr/lib/x86_64-linux-gnu/

I have solved it by adding these entries in the projects ".pro" file and then generating again the Makefile with qmake.
The entries are:
QMAKE_CFLAGS += -no-pie
QMAKE_CXXFLAGS += -no-pie
QMAKE_LFLAGS += -no-pie -fPIC
LIBS += -llua -ldl -L/usr/lib/x86_64-linux-gnu/
