The command `pkg-config --libs cblas` returns "-lcblas". However, no library file libcblas.a is present, causing building of some software packages depending on this library to fail. On the other hand, the Win64 toolchain package mingw64-x86_64-cblas (see https://cygwin.com/cgi-bin2/package-cat.cgi?file=x86_64%2Fmingw64-x86_64-cblas%2Fmingw64-x86_64-cblas-3.7.0-1&grep=cblas) does comport the library usr/x86_64-w64-mingw32/sys-root/mingw/lib/libcblas.dll.a . Am I missing something during Cygwin installation?
