[Ipopt] Is there an option to disable Matlab interface at configure ?

[Stefan Vigerske]

Hi,

no, currently it doesn't seem so.

With the following patch to Ipopt/configure, you can use
--without-matlab-home to disable the check for Matlab.
This will also be in the next release and has been committed to the svn 
repo in trunk and stable/3.12.

Best,
Stefan
