How to install pg_cron on Big Sur Apple M1?

• I am trying to install pg_cron on my local machine Big Sur M1 for development https://github.com/citusdata/pg_cron
• I cannot find any instructions on how to install this on M1
• sudo yum install -y pg_cron_12 does not work
• sudo apt-get -y install postgresql-12-cron doesnt work either
• My PostgreSQL version is 13.4, how do I install pg_cron

You'll probably have to install from source. The documentation describes that:

git clone https://github.com/citusdata/pg_cron.git
cd pg_cron
# Ensure pg_config is in your path, e.g.
export PATH=/usr/pgsql-12/bin:$PATH
make && sudo PATH=$PATH make install

You will need GNU make, a C compiler and the PostgreSQL headers installed; other dependencies have to be found out the hard way, as the documentation is silent about them.
