Installing Cmake in AiiDAlab container

Dear Community,

I am interested to install critic2 (GitHub - aoterodelaroza/critic2: Analysis of quantum chemical interactions in molecules and solids.) on the aiidalab container (arm64) , for this I need Cmake.
My idea is to have this code in aiidalab as localhost to be used by aiidalab_qe.

How can I install the appropriate Cmake, I was wondering if this should be done by changing the image

or

Should i just access the docker as a root-user and do it via sudo apt-get ?

best

Andres
