If we configure qtbase with Ninja Multi-Config, we should use the same
generator when building other repositories as well, to ensure that
all repositories have the same set of configurations (debug and
release). To do that, the Coin instructions will call the
qt-cmake-private wrapper which records the generator used.
For standalone tests continue to use qt-cmake, so that only a single
configuration is built (no need to build tests in both debug and
release mode). The configuration built will be the first one from
the initial list with which qtbase was configured (usually
RelWithDebiInfo). This is ensured by the
QtBuildInternalsExtraConfig.cmake file.

This allows doing debug_and_release builds with Ninja on all
platforms.
The "Ninja Multi-Config generator" is available starting with CMake
3.17.
Desired configurations can be set via CMAKE_CONFIGURATION_TYPES.
Possible values: "Release, Debug, RelWithDebInfo, MinRelSize".
For example -DCMAKE_CONFIGURATION_TYPES="Release;Debug".
The first configuration is the 'default' configuration which is
built when calling ninja with no arguments.
To build all targets of a certain configuration use "ninja all:Release"
or "ninja all:Debug".
To build all targets in all configurations use "ninja all:all".
Note that the first configuration influences which configuration of
tools will be used when building the libraries for all configurations.
In simple terms, when configured with
-DCMAKE_CONFIGURATION_TYPES="Release;Debug" the release version of moc
is used by AUTOMOC.
When configured with -DCMAKE_CONFIGURATION_TYPES="Debug;Release"
the debug version of moc is used by AUTOMOC.
Framework builds and Ninja Multi-Config don't currently work together
due to multiple bugs in CMake, which ends up generating an invalid ninja
file with duplicate rules. There are also issues with placement of the
debug artifacts.
This will be handled in a follow up patch after CMake is fixed.
