No documentation for using Ninja with CMake

https://doc.qt.io/qtcreator/creator-build-settings.html#cmake-build-steps only says:

Qt Creator builds CMake projects by running cmake . --build, which then runs run whatever is needed based on how the project was configured: make, mingw32-make, nmake, or ninja, for example.

What it doesn't say is that to actually use Ninja, you need to:

• Force the kit to use the Ninja generator.
• Install Ninja. This one might be obvious to people familiar with the process, but I assumed it somehow would already be present if CMake was present.
