Answer 1

For me on MacOSX when I initially install CMake by pip, it goes to the similar behaviour.

It was solved by uninstalling CMake by pip, and installing CMake first by brew before installing by pip, and before it installing brew itself, by running in terminal commands from How to run CMake in Mac? answer.

If you're in a virtualenv, then pip uninstall cmake and brew install cmake was needed without the pip install. – Long

Suggestion above is really useful, pip uninstall make and then brew install make seems necessary – Endora

Answer 2

You are talking about two different things:

1. When running cmake --version, you are calling the command line program CMake
2. When using import cmake in a Python program (or interactive session) you are using the cmake Python module.

You are missing the second one. You can install it, e.g. by calling

pip install cmake

I couldnt install qdldl either and found the cmake module was not found error

after a while i noticed that the virtual environment was no active, try activating your virtual environment and then installing cmake in that directory. after that ive opened jupyter labs and tried installing qdldl and it worked.
