2. Building with GNU Fortran compiler and GNU C compiler:
Remarks:
- you have to know the name of the GNU Fortran compiler wrapper
- you do not have to specify a C compiler (with CC); GNU C compiler is recognized automatically
- you should specify compiler flags for GNU Fortran compiler; in the example "-O3 -march=native -mavx2 -mfma funsafe-loop-optimizations -funsafe-math-optimizations -ftree-vect-loop-version -ftree-vectorize" is set
- you should be carefull with the CFLAGS, the example shows typical flags
