Common changes to mingw-w64, ICC on Windows, and MSVC toolchains:
- set similar order of variables and its splitting into sections,
- set similar order of flags in variables and the way they are set.
mingw-w64 toolchain:
- move 'gcc-base.conf' include before setting Windows specific
flags, similar to include 'msvc-desktop.conf' in ICC on Windows
toolchain; this leads to consistency with other toolchains
and allows to safely override common GCC variables with Windows
specific ones, when needed,
- move 'QMAKE_EXT_OBJ' and 'QMAKE_EXT_RES' variables to the linker
flags section, according to its purpose.
MSVC toolchain:
- set flags order in 'CONFIG' variable, similar to mingw-w64 toolchain.

This works around the inability to build iOS apps for a "generic"
simulator by explicitly setting the Xcode build setting
ENABLE_ONLY_ACTIVE_RESOURCES to NO in order to ensure that all variants
of assets in an asset catalog are built when targeting iOS simulator
devices. Otherwise, we will simply build for whatever the first
simulator in the list happens to be. If the application is then deployed
to a different simulator, some of the assets needed for that device
variant may be missing.
This "helps" QTCREATORBUG-19447 but is not a workaround since this fix
is necessary for command line builds anyways, even though it's unlikely
to crop up in practice there, since one would have to manually deploy
the built application bundle to the simulator using simctl rather than
going through Xcode (which would rebuild for the appropriate device).

When a ObjC++ QObject subclass is listed in the regular HEADERS, qmake
creates a .cpp file. The moc file will then fail to compile, as it
requries ObjC++ headers. Using Q_FORWARD_DECLARE_OBJC_CLASS() can be
used to let the class be parsed by The compiler, but link will still
fail, as the generated methods (e.g. signals) must be built with ObjC++
compiler, in case they have ObjC parameters:
Q_FORWARD_DECLARE_OBJC_CLASS(NSString);
class MyClass: public QObject {
Q_OBJECT
signals:
void objcSignal(NSString * myObj);
};
The canonical workaround for that is including the .cpp file into the
corresponding .mm file. This also offers a compilation speed advantage,
but is somewhat counter-intuitive.
Therefore, we introduce a separate variable which instructs moc to create
.mm files directly.

With 4183475080, Qt fails to build if
qmake is unable to detect the compiler's default include and
library search paths. Clang on non-Darwin systems was missing working
code for the detection.
Unlike GCC, Clang on its own does not print the library search paths
when called with the -v option.
On Darwin, the -Wl,-v option will reach ld64, which will print those paths.
However, neither GNU ld nor gold will print anything useful with just
-v. GNU ld has a --verbose option that does print some search paths, but
those are not the ones used when ld is invoked (via collect2) by GCC or
Clang, so it can't be used.
To make Clang print its library search paths one can use
-print-search-dirs, which however doesn't print include search paths. So
amend the existing code in order to make a second call to clang on
non-Darwin systems. This second call is used for library path detection,
and fixes the build on non-Darwin (tested on Linux).

It is considered slightly faster than the default mode[1],
but on Windows it causes trouble when aborting the build,
it leaves behind zero-sized object files which cause link
error. See discussion in the bug-make mailing list[2].

It prints the warning even if we surround the affected code with
QT_WARNING_DISABLE_GCC("-Wstringop-overflow") (see e4eaa62943),
so we have no alternative other than to disable the warning completely.

System headers like tchar.h need the _UNICODE define, not UNICODE.
While qplatformdefs.h already provides _UNICODE when UNICODE is
defined, users might want to include tchar.h without Qt includes.
This is consistent with Visual Studio's default defines.
