How to set default cmake build system

[anderslanglands]

Hello, rez currently defaults to using nmake on Windows, which is awful. Is there a way to set it to ninja by default instead? I tried adding "cmake_build_system": "ninja" to my .reconfig but no dice. I also tried following through the code to see where it's set but can't find it other than the args parser.

EDIT: I also tried:

{
    "cmake": {
        "build_system": "ninja"
    }
}

This probably seems counterintuitive, but try:
plugins = {'build_system': {'cmake': {'build_system': 'ninja'}}}

If I'm not wrong:
rez has a default build system (cmake), but cmake has a default build system (nmake in this case). I assume what you want is to change cmake's default build_system, not rez default build_system, unless ninja's scope has expanded drastically since I last checked.

Keep in mind that this correlates to the difference between rez-build's -b flag, and --bt + --bs flags. You'll see that when cmake is your default build system, the --bt + --bs flags are cmake-specific flags.

Thanks! That did the trick. My .rezconfig is now:

{
    "default_shell": "pwsh",
    "plugins": {
        "build_system": {
            "cmake": {
                "build_system": "ninja"
            }
        }
    }
}
