How to copy builded c++ deps to temp dir created by cibuildwheel?

[MarshalX]

As you can see in the screenshot, I have a dependencies folder that is used when building. When building, relative paths from the current directory are used. How do I copy the dependencies folder to a temporary folder? I do not see the corresponding placeholder for CIBW_BEFORE_BUILD. Only placeholder for package path ({package}).

My folder structure for understanding:

• tgcalls
  • Libraries
    • macos
      • ffmpeg
  • tgcalls
    • setup.py

pip wheel /Users/runner/work/tgcalls/tgcalls/tgcalls -w /var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/cibuildwheel_vhh3uq9/built_wheel --no-deps

How to get /var/folders/24/8k48jl6d249_n_qfxwsl6xvm0000gn/T/cibuildwheel_vhh3uq9 path in CIBW_BEFORE_BUILD?

My temporary solution

1. I added a new placeholder (temp_dir) for macOS to my cibuildwheel fork (commit)
2. Install cibuildwheel from git in my CI workflow
   • old row pip install cibuildwheel
   • new one pip install git+https://github.com/MarshalX/cibuildwheel@temp-dir-macos-placeholder
3. Add CIBW_BEFORE_ALL with coping of folder with deps into temp dir

env:
    CIBW_BEFORE_ALL: mkdir {temp_dir}/../Libraries && cp -R $LibrariesPath {temp_dir}/../Libraries

I think the new placeholder is a good solution to the current problem. Let me know if I should finalize my feature and create a pull request

I strongly suggest to move setup.py one level up or use the environment variable inside setup.py to identify the path to external library.

You could use in setup.py construction like os.environ.get("MY_LIBRARY_BASE_PATH", "..")

Did your code build locally with pip wheel command? I think not. If I good remember your fix works only because of the flat structure of tmp directories created by the command pip wheel.

If you use environment variables in setup.py then package placeholder should be enough.

You are right.

Initially, I didn't want to edit the CMakeLists in order to use the cibuildwheel. But this solution is really better. That's exactly what I did. Dziękuję!
