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.
