gentoo & QtCreator: suddenly qt_version_tag error!

[AlterX]

Hello there,
I don't know why, all my Qml projects are giving me the error:

.obj/main.o:(.qtversion[qt_version_tag]+0x0): undefined reference to `qt_version_tag'

I don't really understand what the problem could be, since gcc is working well (I can build library using QtCreator) and there shouldn't be any relation between the Qt used in plasma and the Qt framework bundled with Qt package (v. 5.7.0)

Someone has or had the same problem? How to fix it?

I have a similar problem. I am using Qt5.6.1 on Ubuntu 14.04. My 2 other programs compile and run as intended. But one of my programs which uses caffe, Peak-can libraries and MQTT throws this error - undefined reference to qt_version_tag. file not found. Please help.
