3ac054d6a8 CMake: Re-work configure flags for CMake generators
Remove the -cmake-makefiles configure argument as its meaning was in
essence "do not pass a -G argument to CMake".
Instead, we add the following arguments:
    -cmake-generator <name> to pass -G <name> to CMake
    -cmake-use-default-generator to pass no -G argument to CMake

If none of those arguments is given, we try to autodetect the
generator. If a ninja executable is found, we prefer the Ninja
generator. On Unix we fall back to "Unix Makefiles".
On Windows, we do a poor man's compiler detection and select one of
"NMake Makefiles", "NMake Makefiles JOM" and "MinGW Makefiles".

dbd3c75965 CMake: Teach configure.bat the -cmake argument
The configure scripts need to translate configure options to CMake
arguments. It is not sensible to implement this translation twice, in
sh and Windows batch language, so we're doing this once, in CMake
language.

The configure scripts write their options into config.opt and call a
CMake script that reads config.opt, does the translation to CMake
arguments and calls CMake to generate the build system.

While we're at it, implement some more translations than the sh
configure provided, like -extprefix, -top-level and -skip.

7067b2ca6e CMake: Don't propagate private defines for Qt header modules
Interface libraries like our Qt header modules should not propagated
private defines which are meant only for building a specific Qt
module, and in the case of a header module there is nothing to build.

Exclude the usual private defines we set in qt_add_module for header
modules. This also fixes the content of header module .pri files.

1048d83fc2 Limit OpenGL deprecation silencing on Apple platform to Qt itself
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.

062318feb2 CMake: Fix non-prefix build detection when CMAKE_STAGING_PREFIX is set
It wasn't possible to create a cross, non-prefix build with
CMAKE_INSTALL_PREFIX set to something else but the qtbase build dir
and CMAKE_STAGING_PREFIX set to the qtbase build dir.
This would be equivalent to
    configure -prefix /usr \
              -extprefix ~/my/qtbase/build/dir

Fix this by comparing the qtbase build dir against
CMAKE_STAGING_PREFIX if it is set. We also have to adjust the
QT_BUILD_DIR variable in a similar way.

389c772fd4 CMake: Fix qconfig.cpp for cross-builds
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.

f3c7d22dd0 CMake: Don't use libraries in /usr/local by default on macOS
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.

To fix that we need to use a "-framework OpenGL" linker flag instead

To convince CMake to do that, we have to create a wrapping
OpenGL target which sets an appropriate INTERFACE_LINK_LIBRARIES
property.

So create a FindWrapOpenGL find module to do that on darwin platforms.
Adjust helper.py and our build system to use it.

3ef14c8943 CMake: Fix framework handling for .pri files
Rather than embedding the full absolute path to the framework, we
should instead write a -framework Foo flag.

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.

6d376ea5f4 cmake: Apply symbol visibility settings to Objective-C/C++ sources
Otherwise the Objective-C++ sources will be built with the default
compiler visibility (visible), and then linked with moc-generated
C++ sources that have the Qt overridden hidden visibility, resulting
in linker warnings such as:

  ld: warning: direct access in function 'X' from file 'moc_foo.cpp.o'
  to global weak symbol 'Y' from file 'bar.mm.o' means the weak symbol
  cannot be overridden at runtime. This was likely caused by different
  translation units being compiled with different visibility setting

21b5c7875c Raise the Android SDK build requirement to lvl 28 - compile fix
First of all cmake and qmake used a different standard.

Secondly, the qmake logic enforced lvl 23 (if it was installed which
is the case on the failing machine). When this is combined with
f71a400bf6 which requires lvl 28 API to build, the android build fails to compile.
cmake logic was even worse as it enforced lvl 21 API to be used if installed.

This change requires pick to 5.15 as f71a400bf6 was picked as well.

Pick-to: 5.15

d7efb2a419 CMake: Fix include paths for AUTOMOC when using frameworks
The qml app was crashing when used by qtdeclarative auto tests. It
complained about unregistered QML types. qmltyperegistrar didn't
create registration info for these types. moc didn't output class info
about these types because the build system didn't provide the proper
include paths.

In qmake land, moc was given 2 sets of paths when building a module:
the non-installed framework dirs as -F flags, and also the
$repo_build_dir/include paths as regular -I flags.

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
paths to transform them into framework include paths
(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
$repo_build_dir/include as public include paths, but only via
BUILD_INTERFACE aka when building Qt itself.

Also pass -F flags by specifying framework include paths in the
pattern that AUTOMOC expects.

Fixes the following qtdeclarative tests
 tst_qdebugmessageservice
 tst_qqmlinspector
 tst_qqmlenginedebuginspectorintegration
 tst_qqmlpreview

e2b2cd9397 CMake: Improve automatic compiler embedding into the Qt toolchain
Embedding the initial CMAKE_CXX_COMPILER into qt.toolchain.cmake
breaks Boot2Qt builds, because the CXX environment variable is not
used anymore when building qtsvg or other projects.

Disable automatic embedding when cross-compiling, while keeping it
enabled for non-cross-compiling cases (to keep Windows and
and ICC configurations working).

Allow opting in or out of the embedding in case if the default is
wrong, via QT_EMBED_TOOLCHAIN_COMPILER.

Assuage the fears in the previous commit, by actually querying and
using the public defines set on a target, rather than hardcoding one
single QT_FOO_LIB define + the extra namespace define.

This should future-proof .pri file generation for qmake mixing.

ed20023760 CMake: Fix namespace builds for qmake mixing
While we recorded the namespace define in the CMake generated Targets
file, we also have to record it in qt_lib_core.pri, so that qmake
knows to use the define when building other modules / apps.

It does scare me what other MODULE_DEFINES we might be missing, and
that we should perhaps put all public modules defines into the
generated module .pri files.

06557312d2 CMake: Improve .prl dependency tracking
Previously .prl files were created via add_custom_command with a
POST_BUILD command. This means they were only created after linking
the libraries, and that whenever a relinking happened, dependees had
to rebuild many parts of their target.

Ideally we would use generator expressions in the OUTPUT argument, but
versions up-to CMake 3.18 don't support doing that.

A workaround is to create and depend on a .prl file name without
generator expressions, and as a side effect also create a .prl file
that does use generator expressions, but don't specify it as an
OUTPUT.

This seems to work well, and improves the dependency tracking issue,
at the cost of one more file copy per .prl file whenever it changes.

d2a04cf165 CMake: Fix .prl generation and installation for plugins
The referenced Qt libraries had paths to the build directory, instead
of the $$[QT_INSTALL_LIBS]/ prefix. The reason was two-fold:

1. QT_BUILD_LIBDIR had the wrong value, namely
"${QT_BUILD_DIR}/platforms/qfoo".

2. The QtFinishPrlFile.cmake script was called with a wrong OUT_FILE
parameter, placing the final .prl file in the build lib dir.

As drive-by change, surround arguments for QtFinishPrlFile.cmake that
can contain spaces with double quotes.
This amends 8c8c0f65e3.
