Specify to install libtiff-dev libpng-dev libwebp-dev before installing iio with python

[gardiens]

Hello,
I started a new fresh dockerfile ubuntu 22.04 and I tried to install iio with pip.
I encountered an error while trying to install iio using pip:

pip install iio
Collecting iio

I fixed them by running sudo apt-get install -y libtiff-dev libpng-dev libwebp-dev . Maybe adding this command could help newcomers,
Sincerely,

You can also run "conda install libwebp" in the eogs python environment.
