Installation problem related to obabel

[lotus0905]

I tried to install pharmd in Ubuntu 20.04 but received an error related to openbabel.
So I specified the locations of Include and Library as the error message suggested:
python setup.py build_ext -I/usr/local/include/openbabel3 -L/usr/local/lib
python setup.py install
but received the same error message.
I have installed Cython (pip install Cython) when asked for.
I'd appreciate your help.
