With Ipopt 3.14 (now available as beta), compiling Ipopt with MKL allows 
to choose between both variants of Pardiso by setting linear_solver 
either to pardiso (this is the non-MKL Pardiso) or pardisomkl.
If set to pardiso, then Ipopt tries to load a non-MKL Pardiso library at 
runtime (dlopen()).
