Apple deprecated the entire OpenGL API in favor of Metal, which
we are aware of, so we don't need to see the warnings when building
Qt.
Instead of applying the silencing globally for all Qt consumers,
both internal and external, we now limit the silencing to Qt itself.
That means user code that explicitly uses any of the deprecated APIs
will see the warnings. Note that this does not apply to merely using
any of the Qt OpenGL APIs. The user has to explicitly use the platform
APIs that have been deprecated.
The warnings need to be disabled on a build system level, so that
that they are passed as -D flags on the command line. If the defines
were done in Qt headers (qguiglobal.h e.g.), they would require the
user to always include this header before any of the Apple headers.

This patch modifies the two preprocessor definitions
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH which are exclusively used
by qmake (and not QtCore's QLibraryInfo) to determine the ext prefix
and the host prefix.
In the qmake build of Qt, qmake considers the host prefix as "location
where qmake is installed". This is usually the same as the ext prefix
but can be modified by the user at configure time.
In the CMake build, we don't build tools for the host but always for
the target platform. The QT_HOST_PATH is an external prefix we never
install to. That means, the qmake we build is always installed into
the ext prefix (CMAKE_STAGING_PREFIX or CMAKE_INSTALL_PREFIX).
Therefore, we can calculate the path of <ext_prefix>/bin relative to
<ext_prefix> and use this value for both,
QT_CONFIGURE_HOSTBINDIR_TO_HOSTPREFIX_PATH and
QT_CONFIGURE_HOSTBINDIR_TO_EXTPREFIX_PATH.
The "path of <ext_prefix>/bin relative to <ext_prefix>" is equivalent to
just the "path <prefix>/bin relative to <prefix>", meaning we can
safely use <prefix>, which is just CMAKE_INSTALL_PREFIX.

qmake builds of Qt don't use libraries in /usr/local because the
path is not considered a system path. Only the SDK path should be
used as a source of system libraries.
We should do the same for the CMake builds, which involves a couple of
things.
Tell CMake not to consider /usr/local (and a bunch of other
paths) as system prefix paths.
Disable pkg-config usage which by default is not used in qmake
Windows and macOS builds.
If a user wishes to use libraries located in /usr/local on macOS, they
can explicitly enable the behavior via -DFEATURE_pkg_config=ON.
In addition to enabling pkg-config, that will also disable the system
prefix modification described above.
Implementation notes
To disable pkg-config usage, we set an empty path for
PKG_CONFIG_EXECUTABLE, because there is no other good way. The
downside to this is that a lot of warning messages will be printed
that the pkg-config package can not be found.
The pkg-config feature needs to be computed in QtBuildInternals before
qtbase/src/configure.cmake, because it's too late to do it in that
file where a few qt_find_package calls already exist.
The feature value is also saved to QtBuildInternalsExtra, to make sure
that pkg-config is disabled whenever building another repo.
System prefix adjustment is done by removing paths from
CMAKE_SYSTEM_PREFIX_PATH.
Ideally we would remove also /usr as a path, to match what qmake does,
but that breaks find_program() calls for perl, python, etc.
We have to make sure that qt_find_package does not look in
PATH when looking for packages, which is the default behavior, because
PATH on macOS most likely contains /usr/local.
One last curiosity for future generations is that CMake 3.18+ has
merged a change to prioritise SDK locations over regular /usr/lib.

Rather than embedding the full absolute path to the framework, we

qmake seems to do this by specifying QMAKE_LIBS_FOO in the mkspec.
We'll try to get away with just deriving the name of the framework
from the path, to avoid having to introduce a mkspec equivalent
mapping for CMake.
This doesn't currently handle framework include paths, which qmake
also handled by harcoding QMAKE_INCDIR_FOO in the mkspec, and then
sysrootifying it via mkspecs/common/mac/sdk.prf.
Hopefully that's not really needed, given that -framework flag
should imply include paths as well.

In CMake land we only gave include paths to the non-installed
framework dirs as -I flags, not -F flags.
That's because AUTOMOC checks for a specific pattern in the include

(existence of Foo.Framework/Headers symlink),
and we didn't pass such an include path.
Make sure to mimic what qmake does, and pass -I flags to

Ideally we would use generator expressions in the OUTPUT argument, but

A workaround is to create and depend on a .prl file name without

This seems to work well, and improves the dependency tracking issue,
