env library does not install

[austrowGC]

Apologies if this is obvious, I am new to workflows.
My understanding is that under env I should be able to specify libraries any of the listed extensions might need. However, a project requiring rdkafka, which requires librdkafka, fails to setup with the following.

Run shivammathur/setup-php@verbose
  with:
    php-version: 8.0.16
    extensions: rdkafka
    ini-values: extension=rdkafka.so
    ini-file: production
  env:
    fail-fast: true
    RDKAFKA_LIBS: librdkafka-dev

The following is successful.

      - name: Install librdkafka
        run: sudo apt install librdkafka-dev
      - name: Setup PHP, with composer and extensions
        uses: shivammathur/setup-php@verbose
        with:
          php-version: '8.0.16'

        env:

Support for installing libraries with pecl extensions is in develop branch. It will be in the next release.

Currently, use the install from source API of setup-php to do this.
https://github.com/shivammathur/setup-php/wiki/Add-extension-from-source

- name: Setup PHP
  uses: shivammathur/setup-php@v2
  env:
    RDKAFKA_LIBS: librdkafka-dev
  with:
    php-version: '8.0'
    extensions: rdkafka-arnaud-lb/php-rdkafka@6.0.1

You do not need to specify extension=rdkafka.so in ini-values input.

Appreciate the help. I had previously tried extensions: arnaud-lb/php-rdkafka@6.0.1 because I didn't read the wiki carefully enough.
