Versionless targets in Qt6 are interface libraries that link the
versioned libraries using the INTERFACE link type. This makes the
linking chain more complicated than it can be. Also we miss some
significant interface properties in the versionless targets comparing
to the versioned targets.
The new approach manually generates the versionless targets, instead
of using CMake exports.
For CMake versions < 3.18 we now create a copy of the versioned
targets. The copy includes all the relevant INTERFACE properties from
the versioned targets and imported locations for all configs.
For CMake versions >= 3.18 we now create the versionless target ALIASes
which should behave give the transparent access to the versioned
targets.
Using the QT_USE_OLD_VERSION_LESS_TARGETS flag you may force the
behavor of the CMake versions <= 3.18
The change is partial workaround for QTBUG-86533.

CMakeLists.txt and .cmake files of significant size
(more than 2 lines according to our check in tst_license.pl)
now have the copyright and license header.
Existing copyright statements remain intact

Needed for subsequent change that will check and error out if the
version is lower than 3.16. We do that to ensure all policies
introduced by CMake up to version 3.16 have their behavior set to
NEW.

The tests/auto/cmake project can be configured separately as a
standalone project with qt-cmake, or as part of the overall qtbase
standalone tests.
To do that a bunch of things were done
- Ported all Qt5 strings to Qt6
- Replaced in all projects the use of add_definitions and
include_directories with a target based approach, except for 2 tests
where we check that the old-style approach works, otherwise the
tests would file
- Removed some (possibly unneeded) EGL / OpenGL tests
- Fixed some C++ code
- Added setup code to tests/auto/cmake/CMakeLists.txt to figure out
which modules are available and should be tested
- Fixed Qt6CTestMacros.cmake to be loaded by Qt6Core
- Removed the CMake tests to not be run in qmake builds of Qt because
they would fail anyway
- Enabled the CMake tests to be part of standalone tests
- Disabled auto-passing of the C and CXX compiler cache vars when
cross-compiling so that the tests can somewhat pass on boot2qt.
This is the issue we encountered in
e2b2cd9397
- Ultimately disabled tests for boot2qt, because the -rpath-link
flag is not generated by CMake for some reason.
- Added code to setup the environment when running an executable that
was built as part of the test, so that the proper Qt libraries are
found. This handles both the standalone tests case and separate
project case.
The remaining unported tests are test_import_plugins which requires
quite a bit of work to get some modules and plugins built that were
done as part of the qmake .pro files, test_plugins that checks
some Network plugins which I'm not sure about, and
test_add_big_resource which doesn't work with namespaced builds
and there's no good way of detecting those at the moment either.
