python -m pip install scikit-network/ fails because it is looking for /triangles.cpp:

• scikit-network version: 0.26.0
• Python version: 3.9.6
• Operating System: Debian GNU/Linux 10 (buster) on Raspberry Pi 3

Description

First I installed sknetwork using pip install sknetwork. Installation works well. Then when I import sknetwork I get ModuleNotFoundError: No module named 'sknetwork.topology.kcliques' After trying different things I gave up. Uninstalled with pip and decided to compile from source.

What I Did

git clone https://github.com/sknetwork-team/scikit-network.git
python -m pip install scikit-network/
