[Scip] Problem compiling SCIP 2.0.0 with CLP: SCIPlpiHasDualRay

[michael.winkler@zib.de]

Hi,

there are new methods implemented only in the latest release of Clp.
Please use this more stable version of CLP (1.12.1) which you can
download/check out via:

svn co https://projects.coin-or.org/svn/Clp/release/1.12.1 coin-Clp

Best, Michael
