how did you install this ?

if it was via pip, maybe you have to use pip3 instead ?

On Raspberry pi, do you two python python 2 and python 3? What's raspberry pi model you have? Python 2 is not available anymore. Actually, you install wrong cmake. You will have start all over again. As for me, I have 3B/+; 4B/4g/8g. With 4B, can take at least 45 minutes. Next time used sudo pip3 as root or pip3 as currently folder.. As for now, The officially used python 3. One thing are you using Debian Buster ver 10?
