%package        devel-static
Summary:        CBLAS development files for -static linking
Group:          Development/Libraries/C and C++
Requires:       %{name}-devel = %{version}

%description    devel-static
The cblas-devel-static package contains the CBLAS static libraries
for -static linking. You do not need these, unless you link
statically, which is highly discouraged.
