At the moment, Coin builds tests as a separate qmake invocation
against an installed Qt. We need to support the same with CMake.
Change the tests subdirectory to be a standalone CMake project when
CMake does not detect an existing QtTest target while processing the
subdirectory. If the target exists, it means we are building the whole
repo, if the target does not exist, we need to call find_package
to find the installed Qt.
Refactor and move around a few things to make standalone tests build
successfully:
- add a new macro to set up paths to find QtSetup
- add a new macro to find all macOS frameworks
- add a new macro to set up building tests
- add a new macro that actually builds the tests
- export the INSTALL_CMAKE_NAMESPACE value into the BuildInternals
Config file
- export the CMAKE_BUILD_TYPE value, because a test project doesn't
have a .git subdir and thus defaults to be built in Release
mode, even though qtbase might have been built in Debug, so to
avoid the mixing, the propagate the build type
- stop overriding INSTALL_CMAKE_NAMESPACE and
QT_CMAKE_EXPORT_NAMESPACE inside QtSetup if they are set, because
the tests project doesn't specify a major version, and if we
override the values, the moc / uic targets don't get the correct
major version prefix and configuration fails

Some Linux distros might not have a double-conversion library. Because
it is such an essential library for QtCore, compile and use the
the copy of the library bundled with Qt.
Also change library name to be a proper target with double colons,
so that in case the library is not found for some reason, the CMake
configure step would fail, instead of failing at link time.

It doesn't make much sense to look for X11 related packages on
macOS and Windows by default. Usually they would not be there, and
as a result the configuration step would show a long list of scary
not found packages, and also eat precious configure time.
Change the conversion script to allow putting conditions around
generated find_package calls.
These conditions can be manually set in the conversion script
library mapping, using the emit_if argument,
which we do for the X11 and Wayland related packages.
They are also computed by checking which features use a given library,
and if the feature is protected by a simple emitIf condition like
config.linux, the relevant library find_package call will be protected
by the same condition.
If a developer still wishes to look for all packages, they can define
the CACHE variable QT_FIND_ALL_PACKAGES_ALWAYS to ON.
The relevant configure.cmake files are regenerated in this patch.

To implement this, create a new Qt5BuildInternals package.
All child Qt modules like qtsvg should use
find_package(Qt5BuildInternals) or
find_package(Qt5 COMPONENTS BuildInternals) in the their
top level CMakeLists.txt.
This will make the qt_build_repo() macros available.
For qtbase we slightly cheat, and specify a CMAKE_PREFIX_PATH
pointing to the source folder that contains the BuildInternals
package.
For the other modules we actually use a configured and installed
package Config file.
This change moves variables that used to be written into the
QtCore Config file into the BuildInternals package. This way
things that are relevant only for building additional Qt modules
does not pollute the QtCore package.

Currently to build qtsvg we have some copy-pasted code to set up
the paths for QtSetup and QtPostProcess to be found.
To make it cleaner, introduce two new macros called
qt_build_repo_begin and qt_build_repo_end(). The first one
should be called in a child repo like qtsvg, right after
a find_package(Qt5) call, and the second one at the end of the
repo top-level CMakeLists.txt file.
In order for the macros to work, extract some of the variables
which were set in Qt5Config into Qt5CoreConfig instead. This
makes sure that it works also for find_package(Qt5Core) calls.

A non-prefix build is a build where you don't have to run
make install.
To do a non-prefix build, pass -DFEATURE_developer_build=ON when
invoking CMake on qtbase. Note that this of course also enables
developer build features (private tests, etc).
When doing a non-prefix build, the CMAKE_INSTALL_PREFIX cache variable
will point to the qtbase build directory.
Tests can be run without installing Qt (QPA plugins are picked up from
the build dir).
This patch stops installation of any files by forcing the
make "install" target be a no-op.
When invoking cmake on the qtsvg module (or any other module),
the CMAKE_INSTALL_PREFIX variable should be set to the qtbase build
directory.
The developer-build feature is propagated via the QtCore Config file,
so that when building other modules, you don't have to specify it
on the command line again.
As a result of the change, all libraries, plugins, tools, include dirs,
CMake Config files, CMake Targets files, Macro files, etc,
will be placed in the qtbase build directory, mimicking the file layout
of an installed Qt file layout.
Only examples and tests are kept in the separate module build
directories, which is equivalent to how qmake does it.
The following global variables contain paths for the
appropriate prefix or non prefix builds:
QT_BUILD_DIR, QT_INSTALL_DIR, QT_CONFIG_BUILD_DIR,
QT_CONFIG_INSTALL_DIR. These should be used by developers
when deciding where files should be placed.
All usages of install() are replaced by qt_install(), which has some
additional logic on how to handle associationg of CMake targets to
export names.
When installing files, some consideration should be taken if
qt_copy_or_install() needs to be used instead of qt_install(),
which takes care of copying files from the source dir to the build dir
when doing non-prefix builds.
Tested with qtbase and qtsvg, developer builds, non-developer builds
and static developer builds on Windows, Linux and macOS.

dbus1_linked is only evaluated to true when the dbus package is found.
If it was not found, then it makes no sense to link against the
_nolink target, because no package was found in the first place.
When the package is not found, QtDBus uses a minimal dbus header which
is included with QtDBus sources, so there is no need for the _nolink
target.
This amends cc141cc5c6 and fixes a build
failure on macOS.
