Follow-up Comment #3, bug #57935 (project octave):

Sorry, not the option, the unusual part is linking with a .so file by its full
file name.

I would normally build Octave with '--with-blas=blas' or
'--with-blas=openblas', and then if you have to, include the directory in
LDFLAGS, e.g. 'LDFLAGS=-L/usr/local/gcc-9.2.0_binutils-2.32_isl/lib64'. And
maybe also include a '-Wl,-rpath' option as well, if that directory isn't
already in your dynamic linker search path.

In fact, if you include that -L option in LDFLAGS, configure should
automatically find libopenblas and use it as the BLAS / LAPACK library without
any '--with-blas' option needed.
