Build in Actions failing due to missing bzip2 includes

[alexm98]

My formula fails when building in GitHub actions due to bzlib not being present during configure:

checking whether to use bzlib... "yes"
checking for location of bzlib includes... /opt/homebrew/opt/bzip2/include
configure: error: *** bzlib includes directory /opt/homebrew/opt/bzip2/include does not exist.

The dependencies I added regarding to this are:

depends_on "lbzip2"
uses_from_macos "bzip2"

There must be something that I'm missing. Shouldn't depends_on "lbzip2" be sufficient for this not to happen?

Here is the URL to the actions

lbzip will be in the lbzip directory, bzip from in another directory and bzip from macOS in the command line tools directory.

Maybe, but you're telling configure to look in a path that does not exist here:

      "--with-bzlib-includes=#{Formula["bzip2"].opt_include}",
