Right now the distribution tarball for MSVC only includes the *.dll files for
the supporting libraries, but not the corresponding *.lib files which allow
actually linking to the dll. This means that the current MSVC nightlies cannot
produce dynamically linked binaries as the *.lib files are not available to link
against.
This commit modifies the `LIB_GLOB` used to copy the files around to include the
`lib` variant of the `dll`.
