The argument allows to ignore the condition for source files if they
are used in the Qt code without corresponding guards. The header files
of this kind usually have internal guards, that suppress the error
at the location where they are used, so AUTOGEN is skipped for these
header files to suppress the warnings from CMake. If file belongs to
a module, it will display AUTHOR_WARNING which should urge Qt
maintainers to guard the use of the source file properly.

When we use MSVC to build static libraries, enabling LTCG will
generate very large output, for example, Qt's bundled 3rd party

This is not good if we are building a shared version of Qt and
enabling LTCG at the same time. On Windows Qt's bundled 3rd party
dependencies will be built as static libraries and they will make
the final Qt package way too large. From my side, if I only build

when LTCG is enabled, it become over 2GB. The exe and dlls' size

An MSVC debug-and-release build of Qt with the MySQL plugin requires
separate builds of the MySQL client library: a debug and a release
build. There was no way to specify the debug version of the library.
Now, it's possible to configure Qt like this:
cmake ... \
-DMySQL_ROOT=D:\mysql-connector-c-6.1.11-winx64 \
-DMySQL_LIBRARY_DIR=D:\mysql-connector-c-6.1.11-winx64\lib\vs14
This will automatically detect the include dir and the debug and release
library files. We expect that the debug build of the MySQL client
library resides in a "debug" subdirectory below MySQL_LIBRARY_DIR.
If the automatic detection doesn't work to due a different layout on the
build machine, one can set the variable MySQL_LIBRARY_DEBUG to specify
the debug variant of the MySQL client library.
[ChangeLog][CMake] If pkg-config is not used, a debug build of the MySQL
client library can be specified with
-DMySQL_LIBRARY_DEBUG=<path-to-library>. The debug and release variants
of the library are automatically detected. Setting MySQL_ROOT and
MySQL_LIBRARY_DIR is sufficient in most cases.

Instead of constantly trying to find packages by calling
qt_find_package on each reconfiguration, record which packages were
found during initial configuration. Then on a second reconfiguration,
skip looking for packages that were not found on the initial
configuration.
This speeds up reconfiguration on certain platforms and repos.
Here are some stats for my macOS qtbase build.

skip 13.87s user 5.16s system 96% cpu 19.724 total
Note this is a behavior change from how find_package is used in most
CMake projects, where if a package was previously missing, the
developer can just install the package and reconfigure to pick it up.
With this change, they will first have to remove their CMakeCache.txt
file and configure from scratch, or remove the
QT_INTERNAL_PREVIOUSLY_FOUND_PACKAGES cache variable and reconfigure.
For this reason, we enable this behavior by default only in
-developer-builds.
Builders can also opt in or out by setting the
QT_INTERNAL_SAVE_PREVIOUSLY_FOUND_PACKAGES variable to either ON or
OFF.
Note this behavior does not apply to user projects, or direct
find_package calls (as opposed to qt_find_package).

When submitting applications to the iOS and macOS AppStore the
application goes through static analysis, which will trigger on
uses of various privacy protected APIs, unless the application
has a corresponding usage description for the permission in the
Info.plist file. This applies even if the application never
requests the given permission, but just links to a Qt library
that has the offending symbols or library dependencies.
To ensure that the application does not have to add usage
descriptions to their Info.plist for permissions they never
plan to use we split up the various permission implementations
into small static libraries that register with the Qt plugin
mechanism as permission backends. We can then inspect the
application's Info.plist at configure time and only add the
relevant static permission libraries.
Furthermore, since some permissions can be checked without any
usage description, we allow the implementation to be split up
into two separate translation units. By putting the request in
its own translation unit we can selectively include it during
linking by telling the linker to look for a special symbol.
This is useful for libraries such as Qt Multimedia who would
like to check the current permission status, but without
needing to request any permission of its own.

I am going to keep the current semantics (implicit conversion) up to and

Since we only support a single localization, the development region,
the locale always ends up as 'en_<REGION>', which after QTBUG-104930
is also reflected in the QLocale's uiLanguages(), resulting in the
QTranslator machinery always picking English translation for the app.
As long as we don't explicitly declare CFBundleLocalizations we need
to opt out of the system's behavior of finding the best match between
the app's declared localizations and the user's preferences, which we
can do via the CFBundleAllowMixedLocalizations key.
