This reverts commit 9268cb8085. That was
done in the mistaken assumption that the bootstrap library needs the

Alexandru Croitor b25eb6e0bd CMake: Introduce zlib find script to work around hardcoded iOS SDK
Xcode allows building a project targeting either the device or
simulator sysroot in one single build dir, but for the sysroot
switching to work there should be no linker or compiler flags
referencing absolute paths of a specific sysroot.

During CMake configuration of a project targeting iOS, all found
system libraries will be within one single sysroot, either the device
one or the simulator one, whichever one was passed to
CMAKE_OSX_SYSROOT. CMake will then generate the Xcode project
and pass those absolute paths, which makes sysroot switching within
Xcode not work.

To avoid that, the CMake documentation recommends passing linker and
framework flags of the form '-lfoo' and '-framework bar' instead of
absolute paths. Xcode then takes care of setting the correct framework
search path.

Zlib is one of the libraries found in the iOS sysroot and thus passed
as absolute path.
To avoid that, create a new FindWrapZLIB find script. The target it
creates will pass the absolute path to the library on non Apple
platforms and an -lz linker flag on Apple platforms (macOS and iOS).

To avoid issues with target global promotion when system PNG package
is found, ensure that a found ZLIB::ZLIB target is promoted to global
manually in src/gui/configure.cmake.

Li Xinwei 013abe3206 CMake: Avoid MSVC C4996 warnings
The qmake build system defines _CRT_SECURE_NO_WARNINGS in
mkspecs/features/qt_module.prf, the cmake build system should do the
same thing in qt_internal_add_module().

Adding this definition can avoid warnings like:
warning C4996: 'strncpy': This function or variable may be unsafe.

As a special case, Bootstrap uses add_library() instead of
qt_internal_add_module(), so _CRT_SECURE_NO_WARNINGS should also be
defined in src/tools/bootstrap/CMakeLists.txt.

Giuseppe D'Angelo 8780fbb2eb Build Qt (and client apps using it) with /permissive-
*Not* using /permissive- exposes Qt and client apps to interesting
bugs and/or build failures, (e.g. QTBUG-87225, or
19b5520abf). We demand strict
conformance by any other compiler, it's time to demand it from
MSVC too.

The Windows headers themselves are clean starting from the
Windows Fall Creators SDK (10.0.16299.0), and moreover Qt 6 will
drop WinRT; therefore, the comment in the mkspecs does not apply
any more.

Since /permissive- implies /Zc:referenceBinding, drop that
option. The other implied options are set on MSVC < 2017,
but I leave them in to avoid tinkering with the fragile lists
of C/C++ flags.

Rename the CMake internal helper function to better describe
what it does.

Giuseppe D'Angelo 14090760a8 Long Live QMap as a refcounted std::map!
... and QMultiMap as std::multimap.

Just use the implementation from the STL; we can't really claim that
our code is much better than STL's, or does things any differently
(de facto they're both red-black trees).

Decouple QMultiMap from QMap, by making it NOT inherit from
QMap any longer. This completes the deprecation started in 5.15:
QMap now does not store duplicated keys any more.

Something to establish is where to put the
QExplictlySharedDataPointer replcement that is in there as an
ad-hoc solution. There's a number of patches in-flight by Marc
that try to introduce the same (or very similar) functionality.

Miscellanea changes to the Q(Multi)Map code itself:

* consistently use size_type instead of int;
* pass iterators by value;
* drop QT_STRICT_ITERATORS;
* iterators implictly convert to const_iterators, and APIs
  take const_iterators;
* iterators are just bidirectional and not random access;
* added noexcept where it makes sense;
* "inline" dropped (churn);
* qMapLessThanKey dropped (undocumented, 0 hits in Qt, 1 hit in KDE);
* operator== on Q(Multi)Map requires operator== on the key type
  (we're checking for equality, not equivalence!).

Very few breakages occur in qtbase.

[ChangeLog][Potentially Source-Incompatible Changes] QMap does not
support multiple equivalent keys any more. Any related functionality
has been removed from QMap, following the deprecation that happened
in Qt 5.15. Use QMultiMap for this use case.

[ChangeLog][Potentially Source-Incompatible Changes] QMap and
QMultiMap iterators random-access API have been removed. Note that
the iterators have always been just bidirectional; moving
an iterator by N positions can still be achieved using std::next
or std::advance, at the same cost as before (O(N)).

[ChangeLog][Potentially Source-Incompatible Changes] QMultiMap does
not inherit from QMap any more. Amongst other things, this means
that iterators on a QMultiMap now belong to the QMultiMap class
(and not to the QMap class); new Java iterators have been added.

Alexandru Croitor 26059d1b9b CMake: Allow building bundled 3rd party libraries in qtbase
A few things are needed to accomplish that:

- the python scripts do not ignore certain system_foo features anymore
  (it is a hardcoded list for now just to be safe)

- configurejson2cmake now outputs
  qt_find_package(WrapSystemFoo) calls for bundled libraries
  (see below)

- the harfbuzz .pro file is modified to accommodate pro2cmake
  not being able to correctly parse some conditional scopes

- the freetype .pro file is modified to make sure linking of the
  library succeeds without duplicate symbol errors, which qmake
  doesn't encounter due to magical exclusion of cpp files that are
  included in other cpp files (presumably for include moc_foo.cpp
  support)

- feature evaluation for Core, Gui, Network now happens in the
  qtbase/src directory, so that bundled libraries can be conditionally
  built

- for each bundled library there are now two FindWrap scripts:
  - FindWrapSystemFoo which finds an installed library in the system
  - FindWrapFoo which either uses the system installed library or
    the built bundled one depending on a condition

- projects that intend to use bundled libraries need to link against
  WrapFoo::WrapFoo instead of WrapSystemFoo::WrapSystemFoo targets
  (this is handled by pro2cmake).
  Unfortunately manually added qt_find_package(WrapFoo) calls might
  still be needed as is the case for WrapFreetype and others.

- a new cmake/QtFindWrapHelper.cmake file is added that provides
  a macro to simplify creation of WrapFoo targets that link against
  a bundled or system library. The implementation is fairly ugly
  due to CMake macro constraints, but it was deemed better than
  copy-pasting a bunch of almost identical code across all
  FindWrapFoo.cmake files.

- a qtzlib header-only module is now created when using bundled
  zlib, to provide public syncqt created headers for consumers
  that need them. These are projects that have
  'QT_PRIVATE += zlib-private' in their .pro files
  (e.g. qtimageformats, qtlocation, qt3d, etc.)
  This is unfortunately needed due to QtNetwork using zlib
  types in its private C++ API.

The change includes support for building the following bundled
libraries:
- zlib
- libpng
- libjpeg
- Freetype
- Harfbuzz-ng
- PCRE2

The following 3rd party libraries are still using an old
implementation within the CMake build system, and should be migrated
to the new one in the near future:
- double-conversion
- Old harfbuzz

The are a few libraries that are not yet ported:
- system-sqlite
- systemxcb
- maybe others

Among other things, this change allows building qtbase on Windows
without requiring vcpkg.

Alexandru Croitor eaa29378b9 CMake: Fix c++ standard config tests with MSVC
Need to pass additional -Zc:__cplusplus flag when using
MSVC, so that the __cplusplus define has correct values.

Additionally make the option be propagated to consumers of Qt
via the public Platform target, which QtCore links against.
