[Osi] question on installing coin-or cplex interface

[Stefan Vigerske]

Hi,

it looks like configure didn't see the flags to build against Cplex and 
then didn't build OsiCpx.

Are you sure that you actually have the lazylpsolverlibs package installed?

Have a look into the output of configure.

It should be easier to first try building against CPLEX, etc, directly, 
without the lazylpsolverlibs in between.
