[CMake] CMake 2.8.1 RC 3 is ready to try

[Arjen Markus]

Hi Brad,

I will need to check that - PLplot does/did have a file 
CMakeFortranInformation.cmake, maybe that is the culprit.

I will try your minimal project myself, hopefully that will
give the same result, otherwise we will have a mystery at
our hands.

Regards,

Arjen
