[macOS CI] 'tbb/parallel_for.h' file not found

[kadyb]

I tried to fix the problem with the incorrect path to tbb on macOS on CI, but unfortunately without success. tbb is definitely installed.

brew --prefix tbb
#> /opt/homebrew/opt/tbb

find /opt/homebrew -name "parallel_for.h"
#> /opt/homebrew/Cellar/tbb/2022.1.0/include/tbb/parallel_for.h

What I tried:

1. Exporting an environment variable in the terminal:

export PKG_CONFIG_PATH="/opt/homebrew/opt/tbb:$PKG_CONFIG_PATH"

export PKG_CONFIG_PATH="/opt/homebrew/Cellar/tbb/2022.1.0/include/tbb:$PKG_CONFIG_PATH"

2. Setting an environment variable in GH:

- uses: r-lib/actions/check-r-package@v2
  env:
    PKG_CONFIG_PATH: /opt/homebrew/Cellar/tbb/2022.1.0/include/tbb

- uses: r-lib/actions/check-r-package@v2
  env:
    PKG_CONFIG_PATH: /opt/homebrew/Cellar/tbb/2022.1.0/include/tbb/lib/pkgconfig

Thank you for looking into this. It is a bit mysterious, since it works on R-Universe and on https://mac.r-project.org/macbuilder/submit.html (and therefore presumably on CRAN, but I have not tried that yet).

It works on R-Universe and MacBuilder, but that is expected because it has:

checking Intel TBB exists:... no
configure: WARNING: to support parallel processing install TBB devel or update the PKG_CONFIG_PATH environment variable

On CRAN for macOS tbb is also missing because I don't see there is a recipe for it?
