[Ipopt] DPOTRF missing in Lapack

[Stefan Vigerske]

Hi,

when you look into ~/src/Ipopt-3.5.5/build/Ipopt/inc/config_ipopt.h, do
you have COIN_HAS_LAPACK defined there?
If so, do make clean, recompile, and try again.
Otherwise remove the build directory, and do a new configure and build.
If configure found lapack, then it should have setup config_ipopt.h in a
way that COIN_HAS_LAPACK is defined.
