Hello!

I have created a virtual environment for anaconda with the following command. (I am doing this on Windows 10)

conda env create -f environment.yaml
conda activate mesh_funcspace

Then, when I tried to compile it, I got the error below.

(mesh_funcspace) D:\occupancy_networks>python setup.py build_ext --inplace

I think the main error is that m.lib is not found, but how can I solve this?

Thank you in advance for your help.
