The action downloads and caches both CMake version 3.24.2 and Ninja version 1.11.1.
To keep your workflow updated to last CMake and Ninja use:
uses: lukka/get-cmake@latest
Or pin your workflow to a CMake version:
uses: lukka/get-cmake@v3.24.2
The version of Ninja is the last at the time of the CMake release.
Enjoy!
