Installation Issue - no rule to make target

I am installing root on my laptop which runs the latest version of macOS (Big Sur 11.4). I need root for python3 so I am trying to build it and was using the following commands:

git clone GitHub - root-project/root: The official repository for ROOT: analyzing, storing and visualizing big data, scientifically
mkdir build
cd build
cmake …/root
make -j8

cmake didn’t give any warnings but the build failed at 90%. I pasted the last bit of output below

make: *** [all] Error 2

While we should be able to make ROOT compile on your Mac, if you don’t need a version compiled from sources it is probably quicker to use a prebuild 6.24 release. We have some instructions on how to install the pre-built binaries.

Are those not only compiled for python 2 for macOS?

Sorry, I overlooked the python3 part. In this case, you can install ROOT from conda or homebrew.
