Install Uno via CMake install

Hi @amontoison, do we need to install a static or a shared library?

Install Uno via CMake install

Thanks for the example. If I wanted both static and shared libraries to have the same name (not sure it's portable though), I could use something like: ```cmake add_library(uno_lib OBJECT...

Behavior when gradient is undefined at starting point

Ah! That's an interesting one :) Uno's ipopt preset performs function scaling (using the gradients at the initial point), THEN perturbs the primal point such that it doesn't sit at...

[WIP] MATLAB interface

Really cool Stefano! Do we need a self-hosted runner with a Matlab license to test the interface in a Github Action or can we do that on the Github runners?

[WIP] MATLAB interface

The Github action runs, well done :partying_face:

[WIP] MATLAB interface

@stefphd sorry for the many changes we're merging into main :sweat_smile: Let me know if you need anything.

`UnoSolver.uno` seems stuck, doesn't terminate

Thanks for your feedback @ForceBru, I'll have a look!

`UnoSolver.uno` seems stuck, doesn't terminate

First remark: in `UnoSolver.jl`, `Bool` options are not parsed properly... This is fixed in https://github.com/cvanaret/Uno/pull/434 and in [UnoSolver.jl v0.1.3](https://juliahub.com/ui/Packages/General/UnoSolver/0.1.3).

`UnoSolver.uno` seems stuck, doesn't terminate

@ForceBru at iteration 2, the current primal iterate is `x = 1 0 -8.28897 10.1 0 12` and for some reason the gradient of the objective is `nan nan nan...
