Trying to setup the repository and failing at the 'make' step for libply_c

cd partition/ply_c

What did you set CONDAENV to?

What did you set CONDAENV to?

I set it to the conda virtual environment I am using for this repo.
CONDAENV=/home/anaconda3/envs/superpoint/

@loicland
The issue was with the anaconda version of python
I gave libpython3.8m instead of libpython3.8.
The following command worked

cmake . -DPYTHON_LIBRARY=$CONDAENV/lib/libpython3.8.so -DPYTHON_INCLUDE_DIR=$CONDAENV/include/python3.8 -DBOOST_INCLUDEDIR=$CONDAENV/include -DEIGEN3_INCLUDE_DIR=$CONDAENV/include/eigen3
make

Thank you for your time
