Dependencies of dependencies to lib

[AlbertoCasasOrtiz]

This branch was not passing CI checks on Ubuntu and this pull request fixes it.

Brief summary of changes

While building opensim-core's dependencies, some required libraries were not copied to the lib folder (those libraries are dependencies of the dependencies, like ipopt, colpack or numps). I added some cp instructions to the script build.sh in order to copy them.

Testing I've completed

This has passed CI in my fork (for Ubuntu and Windows) and completed the conda build step in local.

Looking for feedback on...

A way to do the copy automatically while building the dependencies, instead of having to copy them manually in the script.

Thanks @AlbertoCasasOrtiz for working this out. Longer term we need to make this copying part of the installation process so that it works for plain API usage, conda, docker or any other derivative work. So, we'll leave this PR open and update the commit hash from opensim-core when ready.

Maintaining both opensim and opensim-moco conda packages in the same repo is a bit messy so I'm thinking of keeping a separate branch (master-with-moco) but keeping that in sync with master would be hard. Other thoughts, ideas?
