Cross.toml is ignored?

[VorpalBlade]

I set up a project that uses Cross.toml to install OpenSSL in the pre-build step as documented here:

[target.armv7-unknown-linux-gnueabihf]
pre-build = [
    "dpkg --add-architecture $CROSS_DEB_ARCH",
    "apt-get update && apt-get install --assume-yes libssl-dev:$CROSS_DEB_ARCH"
]

# Same for the other architectures

This works fine locally, but it seems to be ignored by this action, as I'm getting errors like this: https://github.com/VorpalBlade/chezmoi_modify_manager/actions/runs/4692601025/jobs/8318514294

 error: failed to run custom build command for `openssl-sys v0.9.85`

Caused by:
  process didn't exit successfully: `/home/runner/work/chezmoi_modify_manager/chezmoi_modify_manager/target/debug/build/openssl-sys-84e6b09c34fe3be8/build-script-main` (exit status: 101)

  Install a sysroot for the target platform and configure it via
  PKG_CONFIG_SYSROOT_DIR and PKG_CONFIG_PATH, or install a
  cross-compiling wrapper for pkg-config and set it via
  PKG_CONFIG environment variable.

  --- stderr
  thread 'main' panicked at '

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

This is either a bug, or am I doing something stupid/wrong (quite possible).

Cross.toml is a config for cross-rs/cross. Unrelated to this project.

If you want to use cross-rs/cross in github actions I would recommend using install-action to install it.

[VorpalBlade]

Oh okay, I thought this used cross. Thanks.
