Yes, I wonder if it was a difference in method.  I intentionally did not
install any dlls in the search path when that option was presented.
This way, I could isolate them more easily in preparation for creating
an installer.  It did not ask for the Qt dlls.  It asked for libssh,
zlib1, and libeay32.  It also asked for gcc and libstdc++ until I
learned about those static linker options.  Thanks - John
