CMake build fails if Fortran is enabled but ScaLAPACK is not found

GA: 258546972deca14bf541be8b69d8becfdeed39ff

I try adding -DENABLE_FORTRAN=YES flag during CMake configuration to avoid #158, but build fails:

$ mkdir build
$ cd build
$ cmake -DENABLE_FORTRAN=YES ..

Definitions of gai_diag_seq and gai_diag_std_seq are

which is called by

respectively.

This issue is because the fortran file is compiled only when ScaLAPACK (and LAPACK) is available but ENABLE_F77 macro is defined independently.
