[Trilinos-Users] wrong linking flags order in CMake fortran test

[Denis Davydov]

Dear all,

On GCC 5.2. and 4.8.2 there is an issue while compiling libVerifyFortran.a during CMake configure step.
I would say -lgfortran is not in correct place. It should be further down the line to resolve those _gfortran_st_write and alike.
I have no idea how/why it worked before.

Below are the excerpts from gcc 5.2 on Ubuntu and gcc 4.8 on CentOS.

Kind regards,
Denis
