Install fails on macOS: transitive candle-api build error

[mickeyl]

Hi,

python-can-candle currently fails to install on my macOS machine because the dependency candle-api==0.0.11 fails to build from source.

Environment:

• macOS 26.3 (arm64)
• Python 3.14.3
• pip 26.0

Repro:

python3 -m venv /tmp/candle-repro
/tmp/candle-repro/bin/python -m pip install --upgrade pip setuptools wheel
/tmp/candle-repro/bin/python -m pip install python-can-candle

Install fails while building candle-api with CMake errors about missing directories (libusb-cmake and pybind11).

I opened the underlying issue here:

• candle-api 0.0.11 sdist fails to build: missing libusb-cmake and pybind11 dirs candle_api#2

Just filing this here too because from the user side pip install python-can-candle is currently broken on macOS with this toolchain.

If useful, I can test a patched release quickly on the same setup.
