Use any constrained nonlinear optimisation package with an objective function that always returns 0 and some inequality/equality constraints. See [Survey of Non-Linear Optimization Modeling Layers in Julia](https://discourse.julialang.org/t/survey-of-non-linear-optimization-modeling-layers-in-julia/78168) for a list.
