3264	Solver for algebraic loops	Rüdiger Franke	Marcus Walther	"Currently an FMU with algebraic loop fails because the solver ""Newton"" is not known. The first hurdle can be taken by fixing the capatalization in `FMU(2)GlobalSettings.h` from ""Newton"" to ""newton"" -- or better configure ""kinsol"" as in OMCFactory::ReadSimulationParameter (r25379, r25381)?

Btw. LinSolverOMCFactory only knows ""umfpack"" -- is the default ""kinsol"" in OMCFactory::ReadSimulationParameter correct?

Anyway, the FMU now wants to load `libOMCppKinsol.so` dynamically at runtime. It appears that the setting in `SimulationRuntime/Core/System/CMakeLists.txt`, Line 16 is wrong:
{{{
set_target_properties(${SystemName}_FMU PROPERTIES COMPILE_DEFINITIONS ""DRUNTIME_STATIC_LINKING"")
}}}
Changing to `COMPILE_DEFINITIONS ""RUNTIME_STATIC_LINKING""`, without `D`, the resulting libOMCppSystem_FMU contains an AlgLoopSolverFactory with the intended constructer. But that one crashes.

r25380 adds the rpath for now, so that FMUs with algebraic loops work. This is considered a temporary fix though.

How can one link a reasonable solver for algebraic loops into the FMU?
