make failure; test cases failures

[wei-hsuan-cheng]

Hello, I have built this repo following the instructions.
While as i make in /build
the test cases has failures in motors and rotors; therefore i can not sudo make install it

I have already cloned the newest repo of gafro in gitlab, while this issue is still not resolved.

Having strong interests in both geometric algebra and robotics, I am a big fan of this work. Really excited to see this work!!

The detail log is shown below. Hope this will be helpful for your team.
I built this in my docker container, having ros2 humble environment with cmake version 3.22.1.
