pgAudit Install Not Working Because of Makefile (Postgres 15)

Hi My Makefile supposedly doesnt have an install target. How do I fix this?

I dont understand how it even worked for others. Also, I cant use an updated version of Postgres due to restrictions at my job, for anyone wondering.

Also, here's the instructions I followed:

Clone the pgAudit extension:

git clone https://github.com/pgaudit/pgaudit.git

Change to pgAudit directory:

cd pgaudit

Checkout REL_15_STABLE branch (note that the stable branch may not exist for unreleased versions of PostgreSQL):

git checkout REL_15_STABLE

Build and install pgAudit:

make install USE_PGXS=1 PG_CONFIG=/usr/pgsql-15/bin/pg_config

This is the error:

process_begin: CreateProcess(NULL, sh.exe -c "/usr/pgsql-15/bin/pg_config --pgxs", ...) failed.Makefile:15: pipe: No errormake: *** No rule to make target 'install'.  Stop.

This is my Makefile, which I didnt change from what I found at https://github.com/pgaudit/pgaudit/releases/tag/1.7.0
