b3e01d608e CMake: Use custom install script to support Ninja Multi-Config builds
Calling cmake --install . only installs a single configuration.

To install both debug and release artifacts, the install
invocation needs to be done for each configuration.

To keep the Coin instruction code simpler, delegate the looping
over configurations to a custom CMake script, and use it in the
Coin instructions.

Replace all cmake --install calls in the instructions with calls
to either call_host_install.yaml or call_target_install.yaml.

The path to the script depends on whether we are building
qtbase or another module. In the former case the script should
be called from the build dir, otherwise from the install dir.

The other distinction is whether the host or target env prefix
needs to be added.

f240d94f14 CMake: Install non-main-config tools and executables to a subdir
When using Ninja Multi-Config, we don't want to install a "Release"
moc.exe, and then override it with a "Debug" moc.exe.

Because it doesn't seem possible to exclude installation of targets
per configuration, put the non-main configuration tools into
configuration specific subfolders like "bin/Debug", so no overriding
happens upon installation.

Introduce a new function qt_get_install_target_default_args() which
returns install destination arguments for consumption in qt_install()
calls. The function adds the config-specific suffix to the destination
for the appropriate configs.

Each call to qt_install *adds* new rules for installation,
which means that export registration needs to happen only on the first
call.

Make sure qt_add_tool doesn't ask qt_add_executable to install
yet again, to create duplicate rules.

Apply the same install arguments logic to qt_add_executable calls.

06b148074a CMake: Allow using single config generators after building with NMC
Where NMC is the CMake Ninja Multi-Config generator.

The first use case is to allow building standalone tests with one
configuration even if Qt was build with multiple configurations.

Another use case is for regular Qt consumers that might use the
generated qt-cmake shell script which does not have the generator
specified (as opposed to qt-cmake-private).

Another detail is to use the first configuration from the initial
Qt configurations list (CMAKE_CONFIGURATION_TYPES) when building
standalone tests with a single config generator, so that it doesn't
default to Debug, but rather to the provided first configuration.

This matches qmake behavior, where on Windows with a
debug_and_release configuration, tests are still built against
release.

bf315c5526 CMake: Make build system of installed Qt more relocatable
Aka handle CMAKE_INSTALL_PREFIX in a more relocatable way.

The following story inspired this change.

If a user wants to build a Qt repo into a different install prefix
than the usual Qt one, this will fail configuration because we
look for various things like syncqt, qdoc, etc relative to
CMAKE_INSTALL_PREFIX, which will now point to a different location
where none of the above tools are located.

The intent for such a use case is to support building Qt packages with
Conan, which sets a random install prefix when configuring a repo.

The idea is to derive the qt prefix dynamically from the
QtBuildInternals package location. Essentially it's a reverse relative
path from the QtBuildInternalsConfig.cmake file to the install prefix
that was specified when initially configuring qtbase.

Once the dynamic prefix is computed (so we know where the possibly
relocated Qt is), we can find tools like syncqt and qdoc.

This is an initial attempt to support a use case like that.

More design work will probably needed in case if tools / libs need to
be found in a location different than the Qt install prefix (so
support for multiple install prefixes / search paths).

An example of such a case would be when building qtdeclarative and
qtquickcontrols2 as Conan packages in one go. Most likely the
qmltyperegistrar tool will be located in the random install prefix
set by Conan, so building qtquickcontrols2 might fail due to not
finding the tool in the original Qt install prefix.

As to the implementation details, the change does the following:
- Dynamically computes and sets the
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX variable when
  find_package()'ing QtBuildInternals. It's an absolute path
  pointing to where the relocated Qt is.

- When building qtbase this variable is not yet available (due
  to QtBuildInternalsExtra not existing), in that case we set
  the variable to the absolute path of CMAKE_INSTALL_PREFIX
  (but only for the initial qtbase configuration).

- Remove QT_BUILD_INTERNALS_ORIGINAL_INSTALL_PREFIX which was used
  for standalone tests purposes. It's not needed now that we compute
  the location of the Qt prefix dynamically.

- The Unixy qt-cmake and qt-cmake-private shell scripts now
  use a relative path to find the toolchain file we created.

- The toolchain file also dynamically computes the location of the Qt
  packages, and adds them to CMAKE_PREFIX_PATH.

- A lot of existing CMAKE_INSTALL_PREFIX uses are replaced with
  QT_BUILD_INTERNALS_RELOCATABLE_INSTALL_PREFIX. This includes finding
  tool locations, mkspecs dir, path environment setup for tools, etc.

- Some places still use CMAKE_PREFIX_PATH in the following cases
  - When determining paths while configuring qtbase (valid cases)
  - When I wasn't sure what the behavior should be, so I left them
    as-is (an example is documentation generation, do we want to
    install it into the random Conan prefix, or into the main prefix?
    Currently it installs in the random prefix).

Note that relocating a Qt installation does not work for non-prefix /
non-installed builds, due to hardcoded paths to include directories
and libraries in generated FooTargets.cmake files.

8ddd3ee60b Revert "CMake: qt_find_package() enable debug behavior by default"
It broke configuration of qtwayland standalone tests, due to qtwayland
doing 3 separate qt_find_package(Wayland) calls with the same package
but different arguments in 3 different directory scopes.

The top scope didn't have PROVIDED_TARGETS argument. The rest of the
scopes did have the arguments with either Server or Client, but because
of the debug behavior above being enabled by default the dependencies
weren't registered in the Qt6WaylandClientDependencies.cmake file (and
the server equivalent).

The registration didn't happen due to the skipping logic, when a package
is found and the targets already exist.

This led to standalone tests failing to configure because they tried
linking against non-existent Wayland::Client and Wayland::Server
targets.

This reverts commit dd7e40b108.

8ef4edc09e CMake: Fix handling of negated feature config values
Consider a negated feature config value like the following:
qt_feature_config("foo" QMAKE_PUBLIC_QT_CONFIG NEGATE)

If this feature was disabled, it would turn up in both,
enabled_features and disabled_features of module .pri files.
Also, QT_CONFIG would contain foo.

Expected however is that QT_CONFIG contains no-foo, and only
disabled_features contains foo.

Fix this by prepending a "no_" prefix to the value, similar to the
"no-" prefix in the qmake build. The qt_correct_config function was
adjusted to recognize "no_foo" and translate it to the qmakeish
"no-foo" config value.

Config values that start with "no_" but do not correspond to a feature
are left untouched. You can still have values like
"no_valley_too_deep" or "no_mountain_too_high".

f4cd66ff0a CMake: Handle super build non-prefix install prefix correctly
The install prefix in such a case is the qtbase build dir,
and not the qt6 top-level build dir. This caused issues with
certain incorrect paths being generated, including a broken
qt-cmake-standalone-test script, as well as upon reconfiguration
determining that a non-prefix build should be installed.

The fix for a non-prefix build is to check explicitly for
the qtbase build dir. This works both for super and non-super
builds.

67ee92f4d8 CMake: Handle automatic rpath embedding correctly
Instead of using CMAKE_INSTALL_RPATH to embed an absolute path
to prefix/libdir into all targets, use the more sophisticated aproach
that qmake does.

For certain targets (modules, plugins, tools) use relative rpaths.
Otherwise embed absolute paths (examples, regular binaries).
Installed tests currently have no rpaths.

On certain platforms rpaths are not used (Windows, Android,
iOS / uikit).

Frameworks, app bundles and shallow bundles should also be handled
correctly.

Additional rpaths can be provided via QT_EXTRA_RPATHS variable
(similar to the -R option that configure takes).

Automatic embedding can be disabled either via QT_FEATURE_rpath=OFF
or QT_DISABLE_RPATH=ON.

Note that installed examples are not relocatable at the moment (due
to always having an absolute path rpath), so this is a missing feature
compared to qmake. This is due to missing information on where
examples will be installed, so a relative rpath can not be computed.

By default a Qt installation is relocatable, so there is no need to
pass -DQT_EXTRA_RPATHS=. like Coin used to do with qmake e.g. -R .

Relative rpaths will have the appropriate 'relative base' prefixed
to them (e.g $ORIGIN on linux and @loader_path on darwin platforms).
There is currently no support for other platforms that might have a
different 'relative base' than the ones mentioned above.

Any extra rpaths are saved to BuildInternalsExtra which are re-used
when building other repositories.

configurejson2cmake modified to include correct conditions for the
rpath feature.

It's very likely that we will need a new qt_add_internal_app()
function for gui apps that are to be installed to prefix/bin.
For example for Assistant from qttools. Currently such apps
use qt_add_executable().
The distinction is necessary to make sure that relative rpaths are
embedded into apps, but not executables (which tests are part of).

e835a6853b CMake: Fix $ORIGIN rpaths to work when passed on the command line
The CMAKE_INSTALL_RPATH cache var had the PATH type, which made
CMake transform the value into an absolute path, getting rid of the
$ORIGIN value.

Fix that by changing the cache var type to STRING.

Also clean up the all-caps commands, add a usage example and print
the install RPATH.

066e8a4557 CMake: Handle missing packages in project compile tests
If a find_package() in a try_compile project doesn't find a package,
and we then link against a non-existent target, the configuration
failure of the compile test also fails the configuration of the
project.

To avoid that, separate library targets from non-targets, and make sure
to only link against the targets if they exist.

pro2cmake now outputs modified compile test project code which iterates
over targets and non-target libraries, and links against them when
needed.

e0346df1b2 CMake: Handle finding of OpenSSL headers correctly
In Coin when provisioning for Android, we download and configure
the OpenSSL package, but don't actually build it. This means that
find_package(OpenSSL) can find the headers, but not the library,
and thus the package is marked as not found.

Previously the openssl_headers feature used the result of finding
the OpenSSL package, which led to it being disabled in the above
described Android case.

Introduce 2 new find scripts FindWrapOpenSSL and
FindWrapOpenSSLHeaders. FindWrapOpenSSLHeaders wraps FindOpenSSL,
and checks if the headers were found, regardless of the OpenSSL_FOUND
value, which can be used for implementing the openssl_headers feature.

FindWrapOpenSSL uses FindWrapOpenSSLHeaders, and simply wraps the
OpenSSL target if available.

The find scripts also have to set CMAKE_FIND_ROOT_PATH for Android.
Otherwise when someone passes in an OPENSSL_ROOT_DIR, its value will
always be prepended to the Android sysroot, causing the package not
to be found.

Adjust the mapping in helper.py to use the targets created by these
find scripts. This also replaces the openssl/nolink target.

Adjust the projects and tests to use the new target names.

Adjust the compile tests for dtls and oscp to use the
WrapOpenSSLHeaders target, so that the features can be enabled even
if the library is dlopen-ed (like on Android).

0bfbe10ff2 CMake: Implement proper exclusion of tools including installing
The previous approach didn't work for prefix builds. While a target
might be excluded from building via EXCLUDE_FROM_ALL property, when
calling make install it would still try to install the target and
thus fail.

It's not possible to modify an install() command in a post-processing
step, so we switch the semantics around.

pro2cmake will now write a
qt_exclude_tool_directories_from_default_target() call before adding
subdirectories. This will set an internal variable with a list
of the given subdirectories, which is checked by qt_add_executable.

If the current source dir matches one of the given subdirectories,
the EXCLUDE_FROM_ALL property is set both for the target and the
qt_install() command.

This should fix the failing Android prefix builds of qttools.

On Linux it causes issues with the PCH. The PCH file might contain
