Support for alternative linear solver with Schur complement approach #122

Hi, is there any plan to support a linear solver for the with Schur complement approach that is not MA57? I am using qpOASES with the Schur complement approach in an NLP solver (https://github.com/zanellia/feasible_sqp) and it works great (thanks for having developed that!), but the dependency on MA57 makes a bit tricky to distribute/test.

Hi Andrea, there are no plans from my side. AFAIK, Christian Kirches at TU Brunswick is looking for somebody who has the time, motivation, and skills to move Lukas Schork's very efficient code QORE into qpOASES. Lukas' code works with general sparse linear algebra solvers.
