I get the following error when trying to solve an SDP problem with Mosek

```
using Convex, Mosek
... (problem formulation)
solve!(problem, MosekSolver())
```

**ERROR: UndefVarError: MosekSolver not defined**

Mosek.jl no longer supports MathProgBase, which is used by the release version of Convex.jl. So one either needs to use an older branch of Mosek.jl, or use MosekTools and the master branch of Convex.jl. The next release of Convex.jl (i.e. v0.13) should just work with MosekTools.

I also tried with `using MosekTools`

and I’m using the Convex.jl master branch, still the same problem

On master, the syntax should be

```
using Convex, MosekTools
problem = ...
solve!(problem, Mosek.Optimizer())
```
