Missing -lgfortran when linking tests

[tristanvdb]

Hello,

I am build Hydrogen using CMake 3.15.1 and GNU 7.4.0 (OpenBLAS v0.3.9, OpenMPI 4.0.1, Aluminum v0.3.3). Everything is built from scratch including GCC, they are all install in their own directories.

From the command line and errors below, it seems that -lgfortran is missing from the LDFLAGS.

FYI: it is not a blocking issue as I just set LDFLAGS=-lgfortran when running cmake.

Thanks,
-Tristan
