That, plus the fact that SuiteSparse 4.4 and higher has new dependencies
on the suitesparseconfig library from pretty much every other library.
In 4.2, it was only the SuiteSparse_time function, but in 4.4 a lot more
functions have been added to suitesparseconfig.

On a system with dynamic linking configured correctly, all of the
SuiteSparse libraries should be linked against libsuitesparseconfig, so
the application picks it up automatically. I have no idea if this is
done or is possible with the cygwin packaging of SuiteSparse.

If not possible, then we'll have to add tests and add
-lsuitesparseconfig to every SuiteSparse *_LIBS variable.
