Determine one license
There are two licenses declared in this project. In LICENSE file, we declared the license as Apache 2.0; in setup.py we declared the licnese as LGPL. Which one is the correct license?
I would sugget to use Apache 2.0.
I think that was an old license from Uni10. We should all use Apache 2.0.
@IvanaGyro This is resolved?
Do we need setup_macos.py?
Are we completely moving to condo_build? If so, we can remove setup_macos.py
We are using scikit-build-core. As https://github.com/Cytnx-dev/Cytnx/issues/629#issuecomment-3087227199 mentioned, users can just call pip install . to install Cytnx on Mac.
I think the current `'pip install .' is quite good.
