The manual says it is in “CHOLMOD library from SuiteSparse” (
Linear Algebra · The Julia Language).
I cannot find it there:

The manual also says that it is wrapped in " Base.SparseArrays.CHOLMOD". These are the symbols

and CHOLMOD is not there.
I think the code changed, while the documentation lags behind. Does anyone know how to locate that solver?
