[libcamera-devel] Trying to use libcamera with Qt

I was using Raspicam library, but it looks like this one (libcamera) is the one to use if I need to control gains and shutter speed.
I am using Qt5.15. I set Qt to use c++14 and set the include path, #included libcamera/libcamera.h and got:
/usr/local/include/libcamera/libcamera/signal.h:31:17: error: expected unqualified-id before ‘)’ token
SlotList slots();
^
/usr/local/include/libcamera/libcamera/signal.h:119:16: error: expected ‘)’ before ‘...’ token
void emit(Args... args)
I am trying to use this library in a Qt project, but I get a compile error in:
Qt does use the word `slots`, but only for classes marked Q_OBJECT this one is not marked Q_OBJECT.
Can anyone help?
I was able to compile the libcamera-apps (https://www.raspberrypi.org/documentation/linux/software/libcamera/README.md) samples.
