with 40e87491 merged, 'QMAKE_CXXFLAGS' variable in

the similar can be found in 'win32-clang-msvc' and
'win32-icc' toolchains too.
this works for now, because such definitions just duplicates code
from includes, like 'gcc-base.conf', 'msvc-desktop.conf', etc.
but it would became broken, if changes would be applied to
'QMAKE_CXXFLAGS' definitions in that includes, prior
to the redefinitions in 'win32-*/qmake.conf' toolchains.
thus 'QMAKE_CXXFLAGS' definitions in 'win32-*/qmake.conf' toolchains
should not depend on 'QMAKE_CFLAGS' and be done explicitly.
in order to apply this change correctly to 'win32-icc' toolchain,
its 'QMAKE_CFLAGS' variable should become dependent on definitions
in the includes, similar to 'win32-clang-msvc' and
'win32-msvc' toolchains.

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.

clang+libc++ is the only supported way by Google nowadays.
libstdc++ is too old and already fails to build some C++11 apps
e.g. missing std::to_string().
android-g++ mkspec still uses libstdc++ and g++.
Use -isystem to include system headers instead of QMAKE_INCDIR_POST (-I).
