32b596b7b1 configure: CMake: Add -no-prefix option
Introduce a new -no-prefix option that can be used to build Qt without
having to install it.

Currently, -no-prefix is already implied by -developer-build, but
-developer-build also implies -warnings-are-errors and
-feature-private-tests, which not everyone might want to use.

Some Qt builders likely use -developer-build for the no-prefix
behavior, hence we introduce a standalone -no-prefix option to offer
a nicer user experience without -Werror and friends.

Previously it was possible to achieve the same by specifying
-prefix $PWD, but that relies on $PWD expanding property in the used
shell.

The new -no-prefix doesn't depend on the type of the shell and
is shorter to type.

Internally this gets passed by configure as -DINPUT_no_prefix=yes to
CMake, and transformed into a -DQT_FEATURE_no_prefix=ON feature.

The feature also gets automatically auto-detected to ON if
developer-build is set, -prefix is either unset or $PWD.

CMake code should still query QT_WILL_INSTALL to decide whether
files need to be installed or not.

As a drive-by, we now also export QT_FEATURE_developer_build to
be available for querying during configuration of other repos
(previously it was only possible to query FEATURE_developer_build).

158287c726 CMake: Add support building Qt with the 'mold' linker
The mold linker is a new linker for Linux that provides faster link
times compared to BFD ld, ld.gold and lld.

It can be found at https://github.com/rui314/mold

To build Qt with mold, ensure that the binary in your PATH and then
configure Qt with with either

 cmake /path/to/qtbase -DINPUT_linker=mold

or

 /path/to/qtbase/configure --linker mold

The change was tested with gcc 9, clang 10, clang 12, mold
1.0.0. Only qtbase and qtdeclarative (and dependencies) were tested.

0e92ec9728 Remove dysfunctional -coverage configure argument
The -coverage argument merely added compiler flags for the Qt build.  It
was never properly ported to the CMake build, and it doesn't seem
feasible to have configure arguments for every possible compiler option.

The same can be achieved by passing the needed compiler option to CMake,
for example: CMAKE_CXX_FLAGS=-fsanitize-coverage=trace-pc-guard

1981682687 CMake: Propagate sanitizer flags to public projects
Ensure that Qt user projects build with sanitizer flags if Qt was
configured with any of the sanitizers enabled.

To compile Qt with sanitizer support enable any of Qt sanitizer
features.

Passing -DECM_ENABLE_SANITIZERS=address to CMake is NOT supported
anymore.

When configuring Qt using CMake directly, pass
    -DFEATURE_sanitizer_address=ON
    -DFEATURE_sanitizer_undefined=ON
instead of
    -DECM_ENABLE_SANITIZERS=address;undefined

When configuring Qt with the configure script pass
    -sanitize address -sanitize undefined
as usual.

QtConfig.cmake now records the sanitizer options that should be
enabled for all consuming projects based on the enabled Qt features.
This applies to internal Qt builds as well as well as tests an
examples.

The recorded sanitizer options are assigned to the ECM_ENABLE_SANITIZERS
variable in the directory scope where find_package(Qt6) is called.
The ECMEnableSanitizers module is included to add the necessary flags to
all targets in that directory scope or its children.

This behavior can be opted out by setting the
QT_NO_ADD_SANITIZER_OPTIONS variable in projects that use Qt and might
be handling sanitizer options differently.

0e6c4224f0 CMake: Build minimal subset of tests in desktop static builds
Add new configure option -make minimal-static-tests and CMake option
QT_BUILD_MINIMAL_STATIC_TESTS. In conjunction with QT_BUILD_TESTS
it will enable building a minimal subset of tests when targeting
a static desktop Qt build.

In qtbase the minimal subset includes all the auto tests of testlib,
tools, corelib and cmake. In particular this will also do cmake build
tests and qmake build tests (tst_qmake)

Adjust CI instructions to enable building a minimal subset of static
tests when a platform configuration is tagged with the
MinimalStaticTests feature.

Fix and skip a few tests that were failing.

Also looks like it doesn't make sense to enable benchmarks without
having test enabled. So '-DQT_BUILD_BENCHMARKS' enables test as own

584d4be174 CMake: Re-implement configure/qmake's command line handling in CMake
We extend configurejson2cmake to read the "commandline"
information from configure.json. This data is then translated to CMake function
calls and written it into commandline.cmake files.

We extend QtProcessConfigureArgs.cmake to pick up those commandline.cmake
files to feed our command line handling code, which is a
re-implementation of the command line handling in qt_configure.prf.

The command line handler sets INPUT_xxx variables, similar to
configure/qmake's config.input.xxx variables. The INPUT_xxx values are
translated
- to -DFEATURE_xxx=ON/OFF arguments if the input represents a feature,
- to corresponding CMake variables if such a variable is known,
- or to -DINPUT_xxx=yyy CMake arguments.

Configure arguments that have an entry in
cmake/configure-cmake-mapping.md are actually implemented. Other
arguments are likely to need more work.
