QtWebEngineProcess shared libraries

[tkd-alex]

Hi to everyone I'm developing an application with QT.
This is the setup of compiler and qmake:

If I Run qmake (Build -> run qmake) and Build All the operation will end without any problem and application work at the same (zero problem).
This is a screen of my application.

But if I go on debug or release folder of my application and run ./myapp (by terminal) I get this error

/home/alessandro/Qt/5.6/gcc_64/libexec/QtWebEngineProcess: error while loading shared libraries: libQt5WebEngineCore.so.5: cannot open shared object file: No such file or directory

Why the compiler does not even compile libraries ?
Can someone help me? Sorry for my bad english.
