Compilation error on QVersionNumber...

[vanasten]

At an Ubuntu-20.04 system, I got this compilation error while compiling Jamulus-3.6.1;
(qmake "CONFIG+=nosound headless" Jamulus.pro; make clean; make)
(former compilations worked; all dependencies are satisfied)

src/serverlist.cpp: In member function ‘void CServerListManager::CentralServerRegisterServer(const CHostAddress&, const CHostAddress&, const CServerCoreInfo&, QString)’:
src/serverlist.cpp:315:18: error: ‘QVersionNumber’ has not been declared

See #686 and #736 - please use the latest git source or update your Qt to 5.13 or later.

Referring to #736 (comment), I'll close this one.
