Limit CPU cores for ndkBuild with Cmake and Ninja

Question

Before, when I was using ndkBuld for building native code on Android I was able to pass an argument to make to define a number of CPU cores to be used. If I wanted to utilize 4 cores I could add something like this

externalNativeBuild {
    ndkBuild {
        arguments "-j4", "APP_SHORT_COMMANDS=true"
        abiFilters "armeabi-v7a"
    }
}

Can somebody give an advice how can I do something similar with Cmake and Ninja? Is there some equivalent parameter for cmake configuration?

externalNativeBuild {
    cmake {
        arguments "-DANDROID_STL=c++_static"
        abiFilters getAbis()
    }
}

Thanks.

Ok it seems it is a bug / missing feature in NDK. I've talked to some "NDK Googlers" and they were not able to help me either. Hopefully it will be supported in later versions of NDK / AS.
