for historical cygwin package reason cblas is merged with blas,
they are both inside
/usr/lib/libblas.a
/usr/lib/libblas.dll.a
It seems I forgot to amend the cblas.pc to return "-lblas" when
it was added to the lapack package.

I will amend at next release, as workaround you can
modify usr/lib/pkgconfig/cblas.pc manually
