15 The operating system, must be one of: (Q_OS_x)
16
17 DARWIN - Any Darwin system (macOS, iOS, watchOS, tvOS)
18 MACOS - macOS
19 IOS - iOS
20 WATCHOS - watchOS
21 TVOS - tvOS
22 WIN32 - Win32 (Windows 2000/XP/Vista/7 and Windows Server 2003/2008)
23 CYGWIN - Cygwin
24 SOLARIS - Sun Solaris
25 HPUX - HP-UX
26 LINUX - Linux [has variants]
27 FREEBSD - FreeBSD [has variants]
28 NETBSD - NetBSD
29 OPENBSD - OpenBSD
30 INTERIX - Interix
31 AIX - AIX
32 HURD - GNU Hurd
33 QNX - QNX [has variants]
34 QNX6 - QNX RTP 6.1
35 LYNX - LynxOS
36 BSD4 - Any BSD 4.4 system
37 UNIX - Any UNIX BSD/SYSV system
38 ANDROID - Android platform
39 HAIKU - Haiku
40 WEBOS - LG WebOS
41
42 The following operating systems have variants:
43 LINUX - both Q_OS_LINUX and Q_OS_ANDROID are defined when building for Android
44 - only Q_OS_LINUX is defined if building for other Linux systems
45 MACOS - both Q_OS_BSD4 and Q_OS_IOS are defined when building for iOS
46 - both Q_OS_BSD4 and Q_OS_MACOS are defined when building for macOS
47 FREEBSD - Q_OS_FREEBSD is defined only when building for FreeBSD with a BSD userland
48 - Q_OS_FREEBSD_KERNEL is always defined on FreeBSD, even if the userland is from GNU
