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