I am trying to use QSoundEffect from QtMultimedia. I have included the file like so:
#include <QtMultimedia/QSoundEffect>
and used QSoundEffect in my project.
When I try to compile my project after this, I get LNK2019 errors:
1>chatwindow.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QSoundEffect::QSoundEffect(class QObject *)" (__imp_??0QSoundEffect@@QEAA@PEAVQObject@@@Z) referenced in function "public: __cdecl ChatWindow::ChatWindow(class QWidget *)" (??0ChatWindow@@QEAA@PEAVQWidget@@@Z)

How can I tell Visual Studio about the existence of QtMultimedia related files? Qt include and library paths are handled by the Qt VS Tools extension in Visual Studio, so I'm a bit confused.
For some weird reason, it worked when I manually added Qt5's libpath to library paths and Qt5Multimedia.lib to included libraries manually.
