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

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.

For consistency, apply the following renamings:
QT_NO_MAKE_EXAMPLES -> QT_BUILD_EXAMPLES_BY_DEFAULT
QT_NO_MAKE_TESTS -> QT_BUILD_TESTS_BY_DEFAULT
QT_NO_MAKE_TOOLS -> QT_BUILD_TOOLS_BY_DEFAULT
BUILD_EXAMPLES -> QT_BUILD_EXAMPLES
BUILD_TESTING -> QT_BUILD_TESTS
This should help to better convey the difference between "BUILD" and
"NO_MAKE".
To configure tests, but not to build them by default, pass the
following to CMake:
-DQT_BUILD_TESTS=ON -DQT_BUILD_TESTS_BY_DEFAULT=OFF
Analoguous for examples:
-DQT_BUILD_EXAMPLES=ON -DQT_BUILD_EXAMPLES_BY_DEFAULT=OFF
Tools can be excluded from the default build with:
-DBUILD_TOOLS_BY_DEFAULT=OFF
The variable BUILD_TESTING is still available and initialized with the
