  perl:
    env:
      ALIEN_BUILD_PRELOAD: Probe::OverrideCI
    strategy:
      matrix:

          - share
          - system
        perl-version:

    steps:
      - uses: actions/checkout@v2
      - name: Install CI Dependencies
        run: cpanm -n -q Alien::Build::Plugin::Probe::OverrideCI
      - name: Install Project Dependencies
        run: cpanm -n -q --installdeps .
      - name: Configure Project
        run: perl Makefile.PL
        env:
          ALIEN_INSTALL_TYPE_CI: ${{ matrix.install_type }}

DESCRIPTION

This plugin provides an easy way to test both share and system installs using a travis or appveyor environment matrix, without affecting the install type detection of prereqs. Thus if your library Alien::libfoo depends on Alien::gmake you can test both a system and share install for Alien::libfoo while building Alien::gmake using the default (usually system) install and saving build time.

It does this using the appropriate environment variables from the CI tool to determine if the alienfile is in the build root. If you are in the build root, then we use the environment variable ALIEN_INSTALL_TYPE_CI, if we are not in the build root, then we fallback on the existing behavior (either ALIEN_INSTALL_TYPE, or the default for the alienfile itself).

If you want to override the install type on a per-alien basis in a development or production environment (not CI), then Alien::Build::Plugin::Probe::Override may be useful for you.
