The packaging guidelines establishes that BLAS/LAPACK-dependent packages MUST link against FlexiBLAS, instead of a specific implementation directly, so that this can be managed system-wide (see https://docs.fedoraproject.org/en-US/packaging-guidelines/BLAS_LAPACK/#_packaging_blaslapack_dependent_packages). This was implemented as part of https://fedoraproject.org/wiki/Changes/FlexiBLAS_as_BLAS/LAPACK_manager, but reverted in this commit: https://src.fedoraproject.org/rpms/freefem++/c/efc114f4c3615833220689069eb9467679c6dee1 Please, revert back to linking to FlexiBLAS.
