[Ipopt] dsyev present in lapack; output error: dsyev function not found

[Stefan Vigerske]

Hi,

the --with-lapack flag is meant to specify the flags necessary to link 
against a (Blas+)Lapack library, not to specify a directory where Lapack 
source files can be found.
Renaming a source file will also not change the name of the functions 
defined in the source.

Also a lot has changed between Ipopt 3.11 and the 3.13 source that you 
seem to use. Thus, looking at the documentation for current Ipopt 
(https://coin-or.github.io/Ipopt/) might be less confusing. For example, 
regarding Lapack, the easiest should be to use your systems package 
manager to install Lapack 
(https://coin-or.github.io/Ipopt/INSTALL.html#SYSTEMPACKAGES_MSYS), 
which Ipopts configure would then hopefully be able to pick up 
automatically.
