Build fails with Cray Compiler

[bavier]

Building ForTrilinos with the Cray Compiler currently fails due to the use of the -ffree-line-length-none compiler option in CMakeLists.txt, which the Cray Compiler does not recognize/support. The best alternative option would be -N1023 which sets the upper limit on line size to 1023 characters. This appears to be long enough.

@bavier Thanks for letting us know. I think that we may actually no longer need that option as we are able to compile with Flang that requires 132 character limit. Can you please try to compile with that option removed?

Yes, is works with the option completely removed. The Cray Compiler's default line length for free form source is 255.
