• Use --prefix <dir> to set the installation directory.
• Use --compiler <compiler> to specify your Fortran compiler.
• Use --flag '<flags>' to customize compiler flags.

Integrating LAPACK and BLAS in Your fpm Package

• Install ForBLAS and ForLAPACK.
• Copy libforblas.a and libforlapack.a from the lib directory of ForBLAS and ForLAPACK to your fpm package's lib directory.
• Add link = ["forlapack", "forblas"] to your fpm.toml file.
• When using fpm, include --flag '-Llib' to specify the library directory.
