Naras, sorry, but since this involves some Rust code, I fear that you'll have to discuss it with Brian directly. FWIW on the CRAN M1 build machine it seems to use the correct flags:
$ grep fortran/lib /Volumes/Builds/packages/big-sur-arm64/results/4.5/clarabel.Rcheck/00install.out clang -arch arm64 -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -L/Library/Frameworks/R.framework/Resources/lib -L/opt/R/arm64/lib -o clarabel.so init.o -L/Volumes/Builds/packages/big-sur-arm64/results/4.5/clarabel.Rcheck/00_pkg_src/clarabel/src/rust/target/release -lclarabel -L/Library/Frameworks/R.framework/Resources/lib -lRlapack -L/Library/Frameworks/R.framework/Resources/lib -lRblas -L/opt/gfortran/lib/gcc/aarch64-apple-darwin20.0/14.2.0 -L/opt/gfortran/lib -lemutls_w -lheapt_w -lgfortran -lquadmath -F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework -Wl,CoreFoundation $ R CMD config FLIBS -L/opt/gfortran/lib/gcc/aarch64-apple-darwin20.0/14.2.0 -L/opt/gfortran/lib -lemutls_w -lheapt_w -lgfortran -lquadmath I have no idea why it would drop the arch+version specific path (which is the crucial one here - the /opt/gfortran/lib is just a generic fall-back that doesn't have any libraries in our setup).
